Ceramic Coating vs. Powder Coating vs. Ceramic Powder Coating?

An ongoing discussion from 1999 through 2015 . . .


RFQ: I am looking for a company that supplies ceramic materials that can be applied to high temp items, such as automobile exhaust systems. I want to do the actual application in house. We as a company already apply powder coating. We want to expand our operation.

Thermal Spraying-Plasma, Arc and Flame Spray Technology


A. There is probably more than one way to do what you are talking about. Porcelain is one, but has some limitations. The one that I am familiar with is thermal spray (or flame spray, plasma spray, high energy plasma, D gun, J gun or gator gun, etc. You might want to start a search under "thermal spray" or "flame spray". You might also start with Metco, one of the larger vendors. I am sure that they have a web site.

A. If you're already doing powder coatings, you might be interested in "electrostatic enamel powder" like Ferro's PERC powder. The total costs are lower than flame spray. Regards,

A. You may like to contact Almag France Sarl, who are developing an ultra hard ceramic surface for aluminium.

Q. Does anyone know if there are any significant applications of ceramic coatings in the auto industry? I am just curious. I work for an auto supplier and most of our products are zinc alloy plated with chromate conversion coatings. I know there are powder coatings being used, but have not heard of many ceramics.

A. We do ceramic coating of automotive exhausts as well as many other parts. It is becoming widely used in automotive applications because of its durability and it's ability to reduce transferred heat. There are several companies that manufacture such products but we prefer to use TechLine Coatings.

A. Hello gentlemen, We have a simple application of a ceramic based coating that you can apply to almost any substrate, with the proper surface preparation. We are currently modifying applications for the oil and gas industry. We have been working with steam injected into oil through 1500 metre long carbon steel pipes. The product we have is not a brittle ceramic coating, it stays pliable yet works up to 2000 °F. Always remember it must be used for RADIANT heat applications!

High Temperature Black Coatings for Exhaust Systems






A. Look up a company called Techline Coatings. They make a product called BHK or a black satin coating for exhaust systems. It can withstand up to 2000 °F.

Need Coating for Snowmobile Exhaust


Metallurgical and Ceramic Protective Coatings

Q. I have a Steel Muffler for my snowmobile that I wish to sandblast. I was wondering if there was a specific coating I could buy at a auto store. The muffler reaches high temperatures so I really do not want to paint it. Do you have any suggestions? If it would be better to paint it, do you know of any ways to keep the paint on without peeling at high temps?

Thank you!

A. Hi there,

You need to have your exhaust ceramic coated. Smoother exhaust flow, slight horsepower increase, Aluminum color or Black, rust proof, permanent, reasonably priced (twins under $200.00). I would have the job done professionally. It is actually a dip I believe.

Joseph Mathew Levasseur

A. Yes, as stated above a high temp ceramic coating is what is required. These coatings, applied professionally, can withstand temperatures up to 2,000 degrees.

Q. I run a Powder Shop and would like to know what the process involves to shoot high temperature ceramic coatings? By process I mean prep, application, and cure.

RFQ: Also if anyone knows of any Ceramic suppliers ...
Thanks Frank

A. There is at least one paint on the market for houses that claims to be a ceramic. I think that it is just a ceramic filled paint that goes on in a very thick coat. Your description almost makes it a thermal spray process. For a true ceramic coating it would require a high energy system. There are a few companies that do this on a job shop basis, but not many.

James Watts

A. I believe the process is called plasma spraying, if you want to search another term.

James Bonnema

A. To my knowledge, there are two types of "ceramic" coatings. One with organic binder (paint or powder) and the other is thermal spray. I have seen ceramic powder coat applied to exhaust pipes for trucks. If that is what you are looking for, contact powder coating manufacturers like Tiger Drylac or Velspar and find more about their application.

A. There are inorganic powder coatings available. It is a vitreous enamel. It's used as a coating in the appliance industry. It can be applied to a cleaned only or acid etched steel surface (zero carbon preferable). It's cured at somewhere between 1450 to 1580 °F.

Elmer Baldwin
- Mechanicsburg, Ohio, USA


A. If the finish you are talking about refers to exhaust coatings, there is a liquid ceramic/metallic coating available. Application is with a HVLP gun and then partially cured at 500 °F. Rest of the cure takes place on the automobile. There used to be a company (Ceramic Coating Corporation) that glass lined pressure vessels (large ones that store and mix orange juice.) I believe they just preheated the part to an extremely high temperature and applied the product by placing it a cheese cloth type bag and sprinkling the stuff on as the part turned. They did parts for Enerfab. The electrostatic process that Tiger Drylac has is, I believe, for High temperature applications but not a ceramic. It's a silicone based powder. Be careful, thickness greatly influences its capabilities. I hope this helps.

Need ceramic powder for coating exhaust systems


RFQ: We are looking for a company that can supply ceramic powder for coating exhaust systems (manifold, heads) to resist high temperature and improve flow speed of gases.

Q. Hi I was wondering what the difference was from powder coating to ceramic coating for the purpose of engine headers.

Cam Kiebzak

May 28, 2009

A. Hi, Cam. The phrase "Powder coating" today usually implies "plastic powder coating". It means to cover an object with a plastic powder which is subsequently heated enough (to something like 500 °F) to flow and fuse into a coating. True ceramic coating would mean to cover an object with a ceramic frit which is subsequently heated enough (to something like 1200+ °F) to flow and fuse.

So the difference is that "true" ceramic coating is more like coating an object with molten glass or molten ceramic than melted plastic. There is a difference in temperature resistance.

Technology is very wide ranging, with all different kinds of "half-way" coatings possible, and unfortunately the world is full of salespeople who, in an effort to sell their product and make it sound better than it is, deliberately obfuscate and mislead. In this case one way they may do it is to throw a little ceramic dust into a conventional plastic powder coating and then call it a "ceramic coating". The ceramic dust doesn't melt or fuse in this case, it just sits there as a grit in the paint, like sand paint, and may contribute a little something or maybe nothing at all :-(

The best way to look at it may be that the phrase "ceramic coating" has thus been diluted to not mean much, and you must investigate to understand exactly what the particular coating really is. Porcelain coating (vitreous enameling) as used on stove grates is probably the premium finish. In this case several coats of binders followed by several coats of porcelain (melted glass frit) are painted onto the service, with high temperature curing to melt the glass powder. Good luck.

Q. Dear Sir,

Material objects that are attached to steel for super durability, blade shredder size 2 x 8 attached to each other; ceramic-metal reactive welding or silicone base powder? Anyone know how?
RFQ: ... and suppliers?

Sealant protection for a Ceramic Powder Coated panel?

January 20, 2016

Q. Hi, I have recently had the exhausts and panels, of my Triumph Rocket X Roadster, Ceramic Powder Coated in Matte Black. The exhausts obviously carry heat, but the panels don't.


Although this finish is supposed to be resilient, it does succumb to scuff marks and scratches.
I have trawled the Internet for some advice/products/procedures, but to no avail.

Any suggestions would be gratefully received.

A. In the auto paint industry we use a 2k protective clear coat that has been added a Matting agent to protect Matte based coatings that need extra protection.. I have also used Normal 2k clear coat and after it has completely cured used fine sanding paper to kill the gloss and make it Matte again.

Q. I want to put a durable matte black coating on my chrome exhaust tips. They get hot and are subject to the spray of my rear wheels. Is a ceramic coating a good way to go?
