Ceramic coating the heat shield

hsharpag91 · May 8, 2013

I am taking my full Termi system in for black ceramic coating and noticed the heat shield in my box of parts.

I'm wondering what the effect would be on Ceramic coating that piece as well...given that it will also be covered by the new Carbon Fiber heat shield on my R.

I can't imagine it would cost more than $20-30...but don't want to waste the money if its not going to do anything either.

Anyone done this or have any idea if this would help?

An owner on here selling her Tri did it. You can find her ad in the classifieds and PM her. She ended up trading it in on a Multi I believe so she might not be on much anymore.

I cant imagine it would do much of anything personally.

Depends on the coating. I've done turbo heat sheilds and exhaust manifold heat shields on my car and had very good results.

If you have a heat gun and measure the outside of the shield and distance to the heat source the person doing the coating should be able to give you some ideas on the potential reduction.

Doing the Pipe plus the heat shield wont hurt anything and should yield some drop. I'm planning on coating and lining the interior of the heat shield when I get some free time.

My ceramic guy does four or five termi systems a week. He told me he would Be doing that piece in ceramic as well as the rest of the system. From what I can tell, he knows what he's doing.

Besides, if you have it done in black like I'm having done, then you may not need the heat shield at all. (It should look sleek, black, relatively hidden, and be fairly cool temperature-wise. At least that's what I'm hoping for.) My guy isn't charging anything extra for it, so if I sell my heatshield, with carbon fiber and ceramic coating together, I may be able to fetch a better price, (maybe even enough to buy some decent rear sets.

)

I ceramic coated my full exhaust minus the heat shield since I swapped in a carbon fiber one. It still gets hot but not as bad. If you do coat the shield coat both inside and out.

hsharpag91 · May 8, 2013

Thanks all....I'm going to go ahead and have it done. Meeting with a company this afternoon to look at samples and hopefully drop everything off.

As far as overall thermal protection, I would imagine the addition of the heat shield would be minimal in comparison to the pipe as a whole. You may as well though for consistency and it wont hurt. Also if the CF cover were to come off it will be coated already.

Something else to think about, in that you are Ceramic Coating these pipes in black it wont present a problem, but if you were coating them in traditional Bright Ceramic, reattaching the heat shield would likely overheat the pipe under it and damage the finish. Quite frankly, in most occasions these bikes run too hot for Bright Ceramic in general so the heat shield would be the least of your problems.

Assuming the Black Ceramic you are using is rated in the 1700F - 2000F+ range you won't have any problems either way.

Just got my system done with the black ceramic. A word of caution, the little covers that fit on the corners of the mufflers, Part 32 and 33 I do believe, do not have these done as they are some kind of pot metal and cannot stand the 750 deg it takes to do ceramic coating. My exhaust was done for free since they ruined these 2 parts. I ordered from Ducati and they cost $60.00 each and then I just put flat black high temp grill paint on them and it is a perfect match.

Other than that and the Ducati mechanic cussing me as the high temps used to do the ceramic coating does funny things to the metal such as turning round oval. Tech had to beat with rubber mallet to get back to shape and beat muffler to make fit.

Its more likely the parts were damaged in the cleaning process which would involve thermal degreasing / burn-off which operates anywhere from 600F - 1000F. Special care needs to be taken with parts like you've described as well as MAG, and aluminum parts and thin wall SS or TI tubing. These are generally cleaned manually. Keep in mind that many of these thin walled parts are not perfectly "round" to begin with as a result of welding and use so it's common to have to maneuver then in the right orientation to reassemble.

Most all ceramics are baked in the 500F - 600F range.

Id like to do this. Does anyone recommend someone in norcal?

hsharpag91 · May 8, 2013

hmmm....they told me the burn off would be done at 500.

Do you think the thin piece can handle that kind of heat?

I'm having them do the inside and outside of the pipes so hopefully the inside coating will deflect most of the heat out the muffler.

It sounds like there is some confusion in the process or perhaps they didn't understand your question. I can't think of any scenario where 500F would burn anything off in an exhaust scenario. As mentioned earlier, most burn off work is done at 650F - 850F.

Based on "500F" i'd guess they are describing either out-gassing the parts or the actual cure temperature.

I'm not familiar with the actual part to say whether it would hold up but either way the coater should have some lower cure material to work with as well.

They did mine at 750 deg for the cleaning and the ceramic coating. 3 hours on cleaning and 3 hours with ceramic coating. Done at Nitroplating here in Nashville. They said that since it was a new black, as the epa made them change how they did it, that I was getting it free as a test but since the 2 shields disappeared I think the real reason was because they could not stand upto the heat and they "lost them". I called them back and they acted like that was all that I had given them. I know for a fact that they were in the box as someone else on this forum had forgotten to get them coated when they had their exhaust done and I double checked to make sure they were there when I dropped them off.

Oh well it cost me nothing to get done and $120.00 to get the shields replaced. I think there were 11 pieces that were ceramic coated by Nitroplating.

Now if the dealer can get the rivets in to replace the termi stickers I will be happy and post some pictures.

hsharpag91 · May 8, 2013

I called my ceramic plating guy and gave him a heads up on the little pieces. He said they look to be aluminum not pot metal. He didn't think there would be an issue.

That being said he's going to run one tonight with another batch of stuff to see how it holds up to the heat.

Better to lose one than two i suppose.

hsharpag91 · May 8, 2013

He's also going to drill out the rivets and replace which I felt was at least going a little above and beyond.

I'm using a So Cal shop called Xtreme Performance Heat Coatings. So sending it from here in NorCal to SoCal is about $30-35 each way.

They are really reasonably priced, and they do 4-5 Termis per week. They sound like they know what they're doing (we'll find out for sure in a few days) and they include extras for no charge, such as removing the Termi emblem and re-riveting it back on.

All in all, depending on how much NorCal places are doing it for, and whether they have the experience or not, Xtreme may be a deal even with the shipping.

Bottom line, I don't want someone taking a stab at ceramic coating Titanium on my stuff. Let 'em practice some other way, but not on a Termi Ti exhaust, especially since not everybody knows how to ceramic coat Ti).

Ceramic coated my own pipe cover at home, cooked em in the wife's oven ;-)...sneak peak

Didn't feel the need to do the headers as this new heat shield (tho unattractive, at fisrt) really works. May end up doing the fwd header on the right side too.

Done more so for visual effect...now when I look at my bike "23" comes to mind...look like a Michael Jordan #12 in red and black haha

Not sure on that one. In that there are some holes in the "missing parts" department I would take this with a grain of salt. Three hours sounds way to short on a burn off cycle, particularly when its going to take from 30-60 minutes to fully reach temp, which then leaves you with 2-2.5 hours of burn off. Conversely, a three hour cure at 750 is seemingly way too long. Most all materials require a 500-550 min cure for an hour at temp. Some production suppliers will shorten that to 30-45 minutes via higher temps in the 650 to 750 range.

The extended time wouldn't really hurt anything, but it appears to be pointless in that there is little to no difference in material hardness by extending cure time or temp beyond the min requirements.

In that you got your stuff done for free I guess it doesn't matter either way....

Is your "ceramic coating" coming from a spray can??

I am just quoteing the web site: High Performance Ceramic Header Coatings - Nitroplate as to how it is done.

The parts that disappeared were the thin aluminum covers that go on in front of the muffler and bolt on with 2 sets of washers and bolts that are already black. I do not believe they get real hot.
