XTC Silicone Zinc Rich Primer Overview

XTC Silicone Zinc Rich Primer prevents corrosion of metal surfaces exposed to high heat, high humidity, condensation, and salt air.

XTC Silicone Zinc Rich Primer functions much like galvanizing as it locks itself to bare metal surfaces leaving a perfect primed surface for top coating or a great UV stable final finish.

XTC Silicone Zinc Rich Primer protects against rusting and streaking of steel in severe weathering exposures.

XTC Silicone Zinc Rich Primer can be used alone as a finish paint.

XTC Silicone Zinc Rich Primer withstands temps in excess of 1200°F (648°C).

XTC Silicone Zinc Rich Primer is free of fluorocarbons, lead, and chromates.

XTC Silicone Zinc Rich Primer is Grey in color.

Fantastic sealing and filling properties

I used this painting a set of rusty headers and they turned out great. I almost just left the primer on instead of painting because it looked good. After sand blasting and using the KBS Klean, it really stuck well. Very happy with the results!

Antique stove touch up

I have a 50’s Magic Chef double oven and stove. Looks pretty good for 75, but the drip pans in the stove take a beating. As does the lip they suit on. I had to fill some pinholes and cover some raw metal. So far so good! I used the primer and the white. I did finish with a gloss top coat from another company.

Amazing High Temp Primer

I used the KBS high temp primer as an engine base coat before painting it Ford blue. What an amazing product!! The primer went on extremely well and it adhered nicely. Also, it dried in a matter of minutes in where I could spray the engine Ford Blue in the same day. A solid product!! Very impressed and extremely satisfied!! I have attached a few pics.

Awesome high heat primer and coating!

I purchased the XTC Silicone Zinc Primer (aerosol) as well as a pint of Xtreme Temperature Coating (stainless steel) to coat my entire exhaust system and first off, the primer simply sprays on smoothly and evenly with excellent coverage. The coating is amazing even when brushed on which is what I did for a few of my components. Still have yet to install them and give them the actual test but definitely seems very promising!!!

XTC High Temp Primer & Paint for exhaust manifold

I was overall very happy with the XTC Primer and Paint. I decided on XTC's High Temp products to coat the exhaust manifold on my 1989 Lotus Esprit Turbo. The exhaust manifold on this car get notoriously hot! After several spirited runs in My Esprit the paint and primer seems to be adhering very well. I only had one bubble pop up and I am sure that this was my fault as I did get a little inpatient and put a couple thick coats on.. The instructions read use thin coats! Don't ignore this! I am very confident if I had followed the instruction to the letter I wouldn't have gotten the one bubble.. I will definitely use KBS Coatings XTC Silicone Zinc Primer and Paint again in the future,, A great alternative and cost saver to powder coating.

I love this stuff! Another KBS gold star

If you are careful with prep/degreasing/etc, then this will be a great base for the high temp paint. I coated an aluminum intake with this, then went over with KBS aluminum hi-temp paint. Simply outstanding. I'd recommend a heat cure after top coating, rather than curing in use, for exhaust as well, just because of uneven heating. Personally, I wouldn't use this without a top coat, it seems a little porous to me, but apparently you can, according to the label. I suppose heat curing solves that problem, though, so perhaps it's fine. Intake manifolds just aren't going to get hot enough for a good cure, I don't think, so I baked mine in my propane BBQ grill for 30 minutes...champion finish overall. I put several coats on a large 6-cyl intake, and the can is more than half full, so it will go a long way.
