Exhaust Coatings

[juan ruiz]

Whats the choice of coating for your exhaust? I have tried a dozen types of spray cans all of them have failed, try the exhaust wrap, also failed, is there anything out there better that Jet Hot Coating?

Like jet hot there are products from techline coatings. They're ceramic and come in many colors. They're nice. Cermachrome is the popular choice but there is a white, blue, black etc. nice stuff. Keeps heat down.

Anything on these cars must be able to withstand 2,000F.
Caution though that may coatings are nothing more than high temp powdercoat and offer no thermal barrier properties, they just look good.
Jet Hot is one whose product really does reduce radiant heat.

White plasma céramique ( Zircotec) for me.

How is the Zircotec different from the others?

Is this something you're trying to do by yourself? If so, based on your self described failures, chances are you're not going to have access to the prep equipment required to get an appropriate coating to function properly.

If it's a turbo application, traditional Jet-Hot / polished ceramic coating will not survive very long. Polished / bright ceramic coatings are only rated at 1000F - 1100F metal temps which translates to about 1200F - 1500F EGT's. Additionally, short tube headers and exhaust manifolds won't hold up well either even in a normally aspirated application.

For any applications noted above you'll need a "High Temp" Ceramic Coating which is rated at 2000F+. These coatings can endure the abuse of any turbo application.....

CCPCoatings.com,

Thanks for the info, I will let a professional do them this time, my concerns are as you mentioned with the Jet-Hot / polished ceramic coating will not survive very long, that's stuff is hot down there big time.

Hello juan ruiz,

I looked during some time(long enough) before holding(retaining) the treatment(processing) Zircotec, he(it) appeared to me the most serious in this domain. He(it) ya several colors but the white is the most effective, I preferred the efficiency to the appearance.
A small search(research) on the Internet will give you all the information which you would wish, it is an English company.

I have the same coating on my headers, holds up well but under high boost it will blister or melt off in the areas that normally glow red.

Zircotec ?

[Porsche 935]

Yes

You would have normally been able to run their guarantee of one year, me for the moment I have not started my engine yet, I hope that that will be resistant and especially effective for the heat. Would you have a photo of your exhaust Zircotec? Is it some white ceramic?

That is sexy!
My oil drips would destroy that look in no time.

You bring up a good point. This is a HUGE problem for plasma spray coatings like Zircotec & Swaintech. Unlike traditional ceramic coatings, plasma spray coatings are rough and porous, similar to a 36 grit sand paper. As a result they will retain a significant amount of fluids on their surface. Once any kind of automotive fluids get saturated on a hot exhaust pipe you're at risk of a fire. We saw this happen first hand on a local SEMA competition car built by a group of engineering students that compete with other colleges. an oil line leaked near a pipe and eventually the car caught fire in the middle of a competition.

So it goes without saying, if anyone is running this type of coating, you MUST inspect your exhaust system periodically for any signs of fluid saturation. This should be fairly easy at first when the pipes are bright white. Perhaps a bit more difficult when the pipes become dirty with road debris / use.

I've used Jet hot extensively but recently giving Polydyn a try.
Jet hot are quite expensive now compared to their pricing from a few years ago. Polydyn are 1/2 the price with the same warranty, they don't have the same range of colors as Jet Hot but still offer 3-4 decent colors in their Turbo application.

I can post pictures if you're interested.

Photos please.

This is going to turn into another out of body experience, first to find the right stuff, then to find it locally.

What you have just said is not reassuring for me, even if I made every effort to have no oil leak.

After Jet-Hot's HUGE bankruptcy a couple years ago to the tune of 950 million dollars, they were bought by a holding company. Subsequently they raised all of their pricing to pay for the "mythical" lifetime warranty.........

Sure here you go:

I'll post some pics of the Polydyn coated header tomorrow.

Wow..good to know, I had no idea they went bankrupt a few years ago.
