Who Invented Automotive Ceramic Coatings? The Documented History

By Don Paradis — Business Development Manager, Opti-Coat, LLC
Technical Review: Dr. David Ghodoussi, PhD — Founder, Optimum Polymer Technologies

Ceramic coatings have become one of the most important technologies in modern automotive appearance and paint protection.

They have also become surrounded by competing origin stories.

Who invented ceramic coatings? Who first brought them to automobiles? Who coined the term ceramic coating? And what role did Dr. David Ghodoussi and Opti-Coat play in creating the modern professional ceramic coating industry?

Those questions deserve answers based on documentation rather than marketing.

The historical record shows that ceramic coating technology existed decades before automotive detailing adopted it. Modern automotive coatings evolved from earlier industrial ceramic coatings, polymer-derived ceramic materials and silicon-based precursor chemistry developed over many years.

Automotive glass and ceramic coatings then emerged commercially in Japan around 2000.

What happened afterward was not the invention of a single category by one company. Different developers pursued different technologies.

Among the most important of those developments was Dr. David Ghodoussi's work at Optimum Polymer Technologies. Development of Opti-Coat began in 2004, continued through more than three years of testing, and culminated in the 2008 commercial release of a professional-only coating based on Silicon Carbide technology.

Based on the historical documentation identified in this research, Opti-Coat is the earliest documented commercially released SiC-based automotive ceramic coating we have identified.

Just as importantly, its professional-only release helped establish another defining feature of the modern coating industry: the professional ceramic coating installer.

How This History Was Researched

This timeline was assembled using patents and patent-priority records, trademark records, independent laboratory testing, contemporary detailing discussions, historical company records, technical documentation and later manufacturer histories.

Where possible, contemporaneous primary evidence is given greater weight than retrospective manufacturer claims.

That distinction is important.

A later company history can tell us how a manufacturer describes its past today. A dated patent, laboratory report, trademark record or contemporary account tells us what can actually be established from the period in question.

When a source proves that a coating existed but does not establish its chemistry, terminology or commercial status, that limitation is identified.

This is intended to be a living historical record. If credible earlier documentation changes any conclusion or date presented here, the timeline should change with the evidence.

Ceramic Coatings Existed Long Before Automotive Detailing

The automotive detailing industry did not invent either ceramic coatings or the phrase ceramic coating.

One particularly clear primary source is U.S. Patent 2,475,469, filed on November 13, 1945 by Dwight G. Bennett and Clifford M. Andrews.

Its title is simply:

“Ceramic Coating for Metals.”

The patent describes a coating for protecting iron, steel and alloys against corrosion, extreme temperatures and thermal and mechanical shock.

By the early 1950s, ceramic coating was already established industrial terminology.

A 1954 ASTM symposium paper is especially useful historically because it discusses the terminology itself. ASTM explained that the longer expression refractory ceramic coatings had been shortened and that “ceramic coatings” had become prevalent terminology, particularly in industries such as aviation.

That gives us an important starting point:

No company in the modern automotive detailing industry invented the term “ceramic coating.”

The words were part of the materials-science and engineering vocabulary many decades earlier.

The Chemistry That Led to Modern Liquid Ceramic Coatings

Traditional ceramic coatings generally involved conditions unsuitable for automotive paint.

A critical technological step was therefore the development of liquid precursors capable of forming inorganic or ceramic films at progressively lower temperatures.

Polysilazanes became one important family of these materials.

During the 1980s and 1990s, researchers developed increasingly sophisticated silicon-based polymer precursors that could cross-link or convert into ceramic materials.

Japan's Tonen Corporation played an important role in this development.

A Tonen patent with a February 24, 1993 priority date is explicitly titled:

“Composition for Ceramic Coating and Coating Method.”

It describes polysilazane-based ceramic-coating chemistry involving silicon, nitrogen and oxygen. The patent also discusses ceramic systems containing silicon carbide and silicon nitride as possible inorganic components.

A second Tonen patent with a December 28, 1993 priority date is titled:

“Manufacturing Method of Ceramic Coating.”

These documents establish two important facts.

First, polysilazane-based ceramic coating technology existed well before the modern automotive coating industry.

Second, terminology involving ceramic coatings, silicon, nitrogen, carbon, SiC and Si₃N₄ was already part of materials research before the automotive-detailing coating category emerged.

Japan Brings This Technology to Automotive Paint

By the end of the 1990s, this technology was moving toward practical automotive surface protection.

Japanese coating developer Sketch Co. records that in 1999 it worked as a consultant developing applications for Tonen polysilazane technology.

Its corporate history then records that in 2000, ambient-temperature glass-coating technology was transferred for nationwide deployment as car-body coating and Quartz Glass Coating.

Japan Quartz Club independently states that Quartz Glass Coating began sales in 2000.

The product is described as an automotive-body-specific glass coating using perhydropolysilazane, or PHPS, to produce an inorganic protective glass layer on the vehicle.

That is one of the clearest milestones in the history of modern automotive coatings.

By 2000, liquid-applied inorganic automotive glass/coating technology was commercially available in Japan.

The terminology commonly used in Japan was often glass coating rather than ceramic coating.

That does not mean these technologies belonged to entirely unrelated chemical categories. The terminology of automotive coatings evolved along with the products themselves.

A 2001 Patent Makes the Automotive Connection Explicit

The connection becomes even clearer in a Clariant patent with an April 27, 2001 priority date.

The patent describes an inorganic polysilazane coating solution intended for surfaces including:

automobile bodies and wheels, trains, aircraft, glass, plastics and other materials.

Its stated purpose included forming a durable protective coating that avoided the short-lived behavior associated with conventional wax protection.

This is particularly important when discussing modern arguments about polysilazane and SiO₂.

Polysilazane and SiO₂ are not necessarily opposing coating technologies.

Polysilazane may be the precursor chemistry. During curing and conversion, that chemistry can produce a silica-rich inorganic film.

So statements reducing automotive coatings to “polysilazane versus SiO₂” can oversimplify what is actually happening chemically.

Parallel Development in Europe: Ceramic Nanoparticles Enter Automotive Clearcoat

At roughly the same time that liquid-applied glass coatings were emerging in Japan, another branch of ceramic coating technology was entering the automobile through the paint itself.

PPG Industries and Mercedes-Benz jointly developed CeramiClear, a scratch-resistant automotive clearcoat incorporating nanoscale inorganic particles. Contemporary PPG documentation states that the technology was developed with Mercedes-Benz over approximately three years and began commercial production at Mercedes' Sindelfingen, Germany plant in 2002, followed by Bremen.

Mercedes-Benz publicly described the technology in 2003 as a new clearcoat containing microscopically small ceramic particles. During oven curing, the particles formed a tightly cross-linked network within the clearcoat that substantially increased resistance to scratching while helping preserve gloss.

PPG described CeramiClear as using silica nanoparticle technology and marketed it as a major advance in automotive clearcoat chemistry.

This development is historically important, but it belongs to a different branch of the story from Japanese aftermarket glass coatings.

Quartz Glass Coating was a liquid-applied protective layer installed over an existing automotive finish. CeramiClear was part of the factory-applied automotive paint system itself.

The two technologies therefore should not be treated as competing claims to the same invention. Instead, they demonstrate that around the turn of the millennium, ceramic and inorganic coating chemistry was moving into automotive applications through multiple pathways at nearly the same time.

Germany was also home to broader research into sol-gel, silane, polysiloxane and nanostructured coating systems. Companies and research organizations including NANO-X and NTC Nano Tech Coatings were developing inorganic-organic hybrid coating technologies during this period. Those developments help establish the wider materials-science environment from which modern automotive coating technologies emerged, although the surviving documentation should not automatically be interpreted as evidence that every such formulation was intended as an aftermarket automotive paint-protection coating.

The Technology Existed Before the Automotive Industry Agreed on a Name

Early automotive surface-protection technologies were described using several terms:

glass coating, quartz coating, nano coating, resin coating, ceramic-like coating and ceramic coating.

The technology evolved before one marketing term became dominant.

That explains why applying today's terminology retroactively can create confusion.

A coating sold in 2000 as a glass coating may fall within what the modern detailing industry would now broadly discuss alongside ceramic coatings.

Likewise, a product described as producing a ceramic-like film should not automatically be reclassified decades later as a specific ceramic chemistry without supporting evidence.

The historical question therefore cannot simply be:

Who used the word ceramic first?

It must also ask:

What was the chemistry? What did the manufacturer call it at the time? Was it commercially released? And what does the contemporary documentation actually establish?

John Suerth and Matrix Micro-Coatings: What the Historical Record Shows

John Suerth deserves recognition as an early American automotive coating developer.

There is direct documentation establishing that.

An independent laboratory report dated August 2, 2002 identifies Matrix Micro-Coatings, Inc. and John Suerth as the client.

The Advanced Materials Center subjected Matrix-coated materials to 1,008 hours of combined UV and salt-fog exposure. Among the specimens were six pieces of black-painted automotive aluminum.

The report recorded no yellowing, creeping or blistering and little or no measured gloss loss after the exposure period.

That proves:

Matrix Micro-Coatings was developing and testing an automotive protective coating by August 2002.

But there is an equally important question:

What does the 2002 report not prove?

The laboratory report does not identify the Matrix formulation as:

SiC,
Si₃N₄,
SiO₂,
polysilazane,
siloxane,
or another defined ceramic-forming chemistry.

Nor does the independent laboratory report call the material a ceramic coating.

That distinction matters when a 2002 Matrix coating is later described retrospectively as the origin of automotive ceramic coatings.

The report proves that a durable automotive coating existed.

It does not establish the specific ceramic chemistry later attributed to it.

What Matrix Was Selling by 2007

By March 2007, Matrix HyperGloss and HyperSeal were unquestionably commercially available.

A detailed contemporary Rennlist review documents the purchase and application of the complete Matrix system.

The purchaser described the underlying concept as a sealant that bonds over the paint.

More importantly, he reproduced Matrix's own contemporary product description.

Matrix described molecular attraction between atoms of the paint and its “coating resins.”

Matrix then said those materials transformed into thin “ceramic-like films.”

The wording is historically significant.

Ceramic-like is not the same claim as ceramic coating based on a documented ceramic-forming chemistry.

Another professional-detailing discussion from August 2007 provides a second useful contemporary description. An experienced Matrix user described HyperSeal as leaving its own “sealant coating” and discussed HyperGloss and HyperSeal as durable long-term coatings with strong solvent odors and curing requirements.

None of this means Matrix was unsophisticated.

Quite the opposite.

The available evidence suggests Matrix was an unusually advanced surface-protection system for its time.

But the historical evidence presently supports this narrower conclusion:

John Suerth and Matrix Micro-Coatings were early developers of durable automotive protective coatings. The surviving contemporaneous documentation does not establish that the Matrix formulation tested in 2002 was the first automotive ceramic coating.

Who Coined the Term “Ceramic Coating”?

This question can now be answered more precisely.

FEYNLAB currently states that founder John Suerth “first coined the term ‘Ceramic Coating.’”

FEYNLAB also currently describes Suerth as the inventor of ceramic coatings for automotive paint systems and says the lineage of its Ceramic product traces to the first ceramic coating developed specifically for automotive paint.

There are two separate historical questions hidden inside those claims.

Did anyone in modern automotive detailing invent the phrase “ceramic coating”?

No.

The documentary record predates modern detailing by decades.

The phrase appears in U.S. patent literature in the 1940s and was described by ASTM as prevalent industrial terminology in 1954.

Tonen was explicitly using ceramic coating terminology for polysilazane systems in the early 1990s.

The broad claim that a modern automotive-detailing developer coined the words themselves is therefore incompatible with the documented history.

Was Suerth the first to use the term specifically for aftermarket automotive paint protection?

That is a narrower question.

It could potentially be demonstrated with a dated catalog, advertisement, label, technical sheet, patent or other contemporary document showing automotive use of the phrase before anyone else.

We have not located such documentation.

The surviving Matrix evidence from 2007 instead uses terminology including sealant, coating resins and ceramic-like films.

The documentary record therefore does not currently establish Suerth as the person who first applied the term ceramic coating to automotive paint protection either.

That conclusion does not diminish his legitimate place as an early automotive coating developer.

It simply separates documented history from retrospective attribution.

Dr. David Ghodoussi and the SiC Breakthrough

By the time Dr. David Ghodoussi began developing Opti-Coat, automotive glass and inorganic coatings already existed.

His contribution was different.

Dr. Ghodoussi brought a background in polymer chemistry and automotive paint technology to the problem of long-term aftermarket paint protection.

A detailed 2011 account by professional detailer Chad Raskovich dates the beginning of Opti-Coat development and testing to 2004 and says that work continued for more than three years before the product was released in 2008.

The development timeline can therefore be summarized as:

2004 — Opti-Coat development and testing begins

2004–2007 — more than three years of continued development and field evaluation

2008 — professional commercial release

The coating that emerged from that program followed a different chemical pathway from the polysilazane-to-silica systems already established in Japan.

Opti-Coat was developed around Silicon Carbide, or SiC, coating technology.

Opti-Coat's current technical documentation identifies Opti-Coat Pro as an SiC ceramic coating whose pre-polymer cross-links to form a continuous protective film on automotive paint.

This was not simply another name for an existing Japanese glass coating.

It represented a distinct branch in the development of automotive coating chemistry.

August 26, 2008: Opti-Coat Enters Commercial Use

The commercial launch has unusually strong documentary support.

The U.S. trademark record for OPTI-COAT gives:

First use anywhere: August 26, 2008

First use in commerce: August 26, 2008.

That independently anchors Opti-Coat's commercial history to 2008.

The historical record we have reviewed has not identified a commercially released SiC-based automotive ceramic coating predating Opti-Coat.

The most precise claim supported by the evidence is therefore:

Opti-Coat is the earliest documented commercially released SiC-based automotive ceramic coating identified in this research.

This is a narrower claim than saying Opti-Coat invented ceramic coatings themselves.

It is also more meaningful.

It identifies the actual technological contribution Dr. Ghodoussi introduced into the automotive coating market.

2008: Opti-Coat Introduces the Earliest Documented Professional-Only Ceramic Coating Program

Opti-Coat's contribution was not limited to chemistry.

Its original commercial model was also different.

Opti-Coat did not launch in 2008 as an unrestricted retail detailing product.

Raskovich's history of the product states that the original Opti-Coat was not offered to the general public. It was available only to approved professional detailers who signed a waiver acknowledging the application process and risks.

A contemporary May 2010 independent review confirms the same professional-only model, stating that Opti-Coat was sold only to professional detailers who signed a release before purchasing it.

That was important.

Opti-Coat was not positioned simply as another bottle of paint protection.

It was delivered as a professional service.

Proper installation required the detailer to evaluate the paint, correct defects, remove contamination and polishing residues, install the coating correctly and assume responsibility for the finished result.

That relationship between:

manufacturer → professional installer → coating installation → vehicle owner

became one of the defining business models of the modern professional ceramic coating industry.

For comparison, Gtechniq's own corporate history dates the launch of its Accredited Detailer network to 2011.

Opti-Coat's professional-only installation model was already operating before then.

Based on the documentation identified in this research, Opti-Coat represents the earliest documented professional-only automotive ceramic coating program we have identified and played an important role in establishing the professional ceramic coating installer as a distinct specialization within North American detailing.

By August 2008, Optimum's coating technology had progressed beyond laboratory development into real-world beta testing. In a contemporaneous Autopia discussion, professional detailers Anthony Orosco and Ron Harris described testing an as-yet unnamed Optimum coating that chemically bonded to automotive surfaces, formed a measurable protective film, resisted conventional washing chemicals, and was intended to provide multi-year protection.

The discussion also shows that application methods, packaging, pricing, and professional-only distribution were still being evaluated, providing a rare public record of the product before its commercial introduction as Opti-Coat. The same discussion references emerging coating technologies from Japan and Europe, illustrating that a broader international market for durable automotive surface coatings was beginning to develop during this period.

Autopia Forum Discussion of Pre-Release Optimum Coating (2008)

From Detailer to Professional Coating Installer

This change was larger than it appears today.

Before ceramic coatings, detailers primarily sold services built around washing, polishing, correction, waxing and sealant application.

A long-term or permanent coating changed the responsibility of the person applying the protection.

The installer needed to understand paint condition and correction because defects left underneath a cured coating could remain trapped beneath it.

Application quality mattered because the coating was not intended to simply wash away or be routinely reapplied.

The customer was therefore purchasing more than a chemical.

The customer was purchasing:

paint evaluation, preparation, correction, specialized installation and long-term protection.

The professional ceramic coating installer became its own category.

Today, the industry takes concepts such as Authorized Installer, Accredited Detailer, Certified Installer, professional-only coating and manufacturer-backed warranty for granted.

In 2008, that professional coating model was still emerging.

Opti-Coat was built around it from the beginning.

Why Silicon Carbide Matters to the History

Acknowledging earlier automotive coatings makes Opti-Coat's contribution clearer—not smaller.

The early Japanese coating lineage was strongly associated with polysilazane and silica/glass-film technology.

Dr. Ghodoussi pursued a different route.

Opti-Coat developed an SiC-based cross-linking coating architecture intended for long-term automotive paint protection.

The significance is not simply that one chemical abbreviation is different from another.

It demonstrates that the automotive ceramic-coating category did not descend from one formulation or one inventor.

Multiple branches of coating chemistry developed.

Opti-Coat represents one of the most important of those branches.

Its historical importance is therefore not dependent on pretending nothing came before it.

Its importance comes from moving the chemistry forward.

2011: Opti-Coat Brings the Technology to Consumers

The original Opti-Coat remained professional-only.

That changed in 2011.

Raskovich's contemporary account says consumer demand grew as enthusiasts saw professional detailers discussing their experiences with Opti-Coat.

In spring 2011, Optimum released Opti-Coat 2.0, a consumer-oriented version designed with a slower cure and more forgiving application characteristics.

That sequence is historically revealing:

professional development → professional-only introduction → professional installer adoption → consumer adaptation.

Rather than launching a retail coating and later creating a professional program around it, Opti-Coat began with the professional installer.

So Who Invented the Automotive Ceramic Coating?

The historical evidence suggests that the question itself is too simplistic.

There was no single moment when one modern detailing company invented everything now grouped under the term ceramic coating.

The category developed through several overlapping branches of materials science, automotive paint technology and aftermarket surface protection.

Industrial researchers developed ceramic protective coatings decades before modern automotive detailing existed.

Materials scientists developed silicon-based polymers, polysilazanes and other ceramic-forming precursor chemistries capable of producing protective inorganic films.

Japanese researchers advanced polysilazane ceramic-coating technology during the 1990s, and Japanese companies brought liquid-applied inorganic glass coatings to automotive paint around 2000.

At approximately the same time in Europe, PPG and Mercedes-Benz were developing CeramiClear, bringing nanoparticle-based ceramic technology directly into factory automotive clearcoat production by 2002.

John Suerth and Matrix Micro-Coatings were developing and independently testing advanced automotive protective coatings in the United States by 2002.

Gtechniq introduced C1 Crystal Lacquer in 2004, making it another important participant in the formative years of the modern aftermarket coating industry.

Beginning in 2004, Dr. David Ghodoussi developed a different SiC-based automotive coating architecture that became Opti-Coat and reached the commercial market in 2008.

Opti-Coat also introduced another important development: rather than launching first as an unrestricted retail product, it was offered only to approved professional detailers. Based on the documentation identified in this research, Opti-Coat is the earliest documented professional-only automotive ceramic coating program we have identified.

The industry then expanded rapidly.

CARPRO was established in 2009 and helped expand awareness of CQUARTZ and ceramic coating technology internationally.

Nanoshine introduced Ceramic Pro in 2010, contributing to the rapid growth of professional ceramic coatings as a global automotive-protection category.

In 2011, Optimum released Opti-Coat 2.0 for consumers, while Gtechniq launched its Accredited Detailer network as formal professional installer programs became increasingly common throughout the industry.

Seen in this broader context, the modern automotive ceramic coating was not the invention of one company, one chemist or one formulation.

It developed through several technological branches:

industrial ceramic coatings → polymer-derived ceramic precursors → Japanese polysilazane and glass coatings → ceramic nanoparticle automotive clearcoats → early aftermarket coating systems → SiC ceramic coatings → professional installer programs → global expansion of the ceramic coating category.

Each stage contributed something different.

The historical significance of Opti-Coat is therefore not that nothing came before it.

Its significance is more specific: Dr. David Ghodoussi developed a distinct SiC-based automotive ceramic coating architecture, brought it commercially to professional detailers in 2008, and helped establish the professional-only ceramic coating installer model that became a defining part of the modern auto detailing industry.

Trying to assign the entire category to one modern brand obscures how the technology actually evolved.

Dr. David Ghodoussi's Two Contributions to Ceramic-Coating History

Dr. Ghodoussi's contribution is best understood in two parts.

1. Advancing the Chemistry

Beginning in 2004, Dr. Ghodoussi developed and tested the coating technology that would become Opti-Coat.

After more than three years of development, the product reached the professional market in 2008.

The resulting coating introduced an SiC-based approach to automotive ceramic protection.

Based on the historical documentation identified in this research, Opti-Coat represents the earliest documented commercially released SiC-based automotive ceramic coating.

2. Professionalizing the Category

Opti-Coat also entered the market differently.

It was released as a professional-only product available to approved professional detailers, rather than being introduced first as an unrestricted consumer coating.

That helped establish a new professional specialization built around proper paint preparation, correction, coating installation and installer responsibility.

The model became familiar throughout the industry:

professional-only products, authorized installers, manufacturer relationships and long-term coating services.

Opti-Coat was helping define that model during the formative years of the modern ceramic-coating market.

A More Accurate Legacy

Opti-Coat does not need an exaggerated origin story.

Dr. David Ghodoussi did not invent ceramic materials.

He did not invent industrial ceramic coatings.

He did not invent the words ceramic coating.

Earlier automotive glass and inorganic coatings existed before Opti-Coat.

Those facts do not diminish Opti-Coat's place in the history.

They make its genuine contribution easier to identify.

Dr. David Ghodoussi helped move automotive ceramic coatings forward in two important ways: by pioneering a documented SiC-based automotive coating architecture and by bringing that technology to market through a professional-only installer model in 2008.

The chemistry changed how automotive paint could be protected.

The installer model changed how that protection was professionally delivered.

Opti-Coat's legacy is not that nothing existed before it.

Its legacy is that it advanced both the technology and the professional category that followed.

Beyond Ceramic Coatings: A Later Development at Optimum

The development of automotive paint protection did not stop with conventional ceramic coatings.

The same underlying challenge remained: how to protect automotive paint with a liquid-applied system while increasing durability, film build and resistance to physical damage.

That development eventually led Optimum Polymer Technologies to Opti-Shield Liquid PPF, a protection system designed to occupy the space between a traditional ceramic coating and conventional paint protection film.

Opti-Shield is not simply another ceramic coating.

It uses a self-healing resin system combined with ceramic chemistry to create a substantially thicker protective layer than a conventional coating. Rather than relying primarily on a very thin cured film for chemical resistance, gloss and environmental protection, the system is designed to add greater physical protection while remaining liquid-applied.

Unlike traditional paint protection film, there are no pre-cut panels, film edges or seams. The material is applied as a liquid and cures directly on the painted surface.

The result represents another branch in the continuing evolution of automotive surface protection:

wax and sealants → ceramic coatings → professional coating systems → liquid-applied self-healing protection.

Historically, that distinction matters.

Ceramic coatings demonstrated that durable inorganic and polymer-derived protection could be chemically bonded or cross-linked onto automotive paint. Opti-Shield extends that concept by combining liquid application with greater film build and self-healing behavior traditionally associated with protective films.

It should therefore be viewed not as part of the origin story of ceramic coatings, but as an example of where the technology continued to evolve afterward.

Just as Opti-Coat represented a different chemical pathway within the early ceramic-coating industry, Opti-Shield represents a later extension of Optimum's work in liquid-applied automotive paint protection.

Historical Methodology and Corrections

Historical research is only as reliable as its evidence.

For this reason, this article distinguishes between:

primary contemporaneous evidence such as patents, laboratory reports and trademark records;

contemporary third-party evidence such as period product reviews and professional discussions;

and retrospective manufacturer claims published years after the events being described.

A later manufacturer history can provide useful context, but it does not automatically establish historical priority.

If earlier primary-source material becomes available—such as dated technical data sheets, product literature, patents, advertisements, invoices, photographs or laboratory documentation—that materially changes any conclusion presented here, we welcome the opportunity to review it and update this timeline.

The objective is not to assign historical credit based on marketing.

It is to document the development of automotive ceramic coating technology as accurately as the surviving evidence allows.

Technical Review

Dr. David Ghodoussi, PhD — Founder, Optimum Polymer Technologies

Dr. Ghodoussi is a polymer and organic chemist whose professional background includes automotive paint and polymer research. His work helped advance modern automotive clear-coat technology before he founded Optimum Polymer Technologies in 2001. He later led the development of the SiC-based coating technology that became Opti-Coat.

Dr. Ghodoussi reviewed the technical descriptions of coating chemistry and the 2004–2008 Opti-Coat development history presented in this article.
