XTC is a high temperature/heat resistant coating formulated specifically to protect metal surfaces operating at temperatures from 500°F (260°C) to 1500°F (812°C). With proper preparation, XTC provides outstanding adhesion, film integrity, corrosion, weathering and thermal shock-resistance throughout this entire temperature range, and is guaranteed not to burn off!


Engines, Manifolds, Headers, Mufflers • Furnaces, Kilns, Ovens, Stoves • Compressors, Turbines • Stoves (wood, coal, pellet, gas, etc.) • Fireplace hoods, screens, & accessories


Withstands continuous temperature of up to 1500°F (812°C) • Outstanding heat and weathering resistance • Will not peel, flake, or chalk • Long Lasting • Dries for handling in 15 minutes • Once heat cured, is resistant to scratching & marring


Parts that will be immersed • Direct contact with open flame • Cooking surfaces


Steel surface to be primed must be dry and free from dirt, oils, rust, and other contaminants. Sandblasting is the ideal surface preparation as it leaves the ideal anchor pattern for paint adhesion. After sandblasting, use clean compressed air to blow off any residual blast media. Be sure to wear surgical-type gloves when handling to keep natural body oils off the prepared surface.

If not sandblasting, prepare surface by using wire wheel, wire brushing, or abrasive sanding using 60-80 grit paper. This method will provide a surface equivalent to that provided by sandblasting and allow the desired surface profile or anchor pattern.

Wash surface with KBS Klean at a 10:1 (Water/KBS Klean) ratio, rinse and let dry thoroughly to wash away residual oils. Allow surface to thoroughly dry before proceeding.

Mask off areas not to be coated & protect adjacent areas with drop cloth or newspapers.

For best results, apply when XTC and room temperatures are between 60-80° F (16-27° C).


Do not open containers until ready to use. Re-disperse any settled-out pigments by stirring with a paint paddle or power mixer to a uniform consistency. Keep lid on container when not in use.


Theoretical coverage at one mil (25 microns) is 400 (Alum)/300 (All Others) sq.ft. per gallon OR 9.6 (Alum)/7.0 (All Others) sq.m. per liter. Recommended thickness of two mils (50 microns) would require two full coats. Material losses during mixing and application will vary and must be taken into consideration. Expect up to 30% less coverage on rough surfaces. Aerosol can theoretically covers 8 sq. ft.


Ideal application temperatures of air and substrate to be coated are 50-82°F (15-28°C). XTC may be applied by conventional or HVLP spray, airless spray, brush or roller. Do not apply XTC in heavier films than specified since blistering may occur. As with all KBS Products, multiple very thin, covering coats is always the best practice.

For corrosion protection and rust protection, metal surfaces should always be primed with XTC Primer which is our silicone zinc high temperature and corrosion resistant primer (approx. 1.0 mils/25um DFT), then top-coated with one coat (1.0 mils/25um DFT) of the XTC color of your choice.

If not using XTC Primer, apply two coats (1.0 mils/25um DFT each) of XTC allowing at least 8 hours between coats and allow the second coat to dry at least 8 hrs before subjecting surface to any heat. The number of coats of XTC needed depends upon service conditions of equipment.



Spray pressure of 35-45 psi for siphon/pot guns and 25-35psi for gravity/top container guns.

Spray tip size of 1.0-1.5.

Thinning is not generally required but if needed 5%-10% is normally adequate. Use KBS #1 Thinner only which is a slow evaporating solvent. Do not reduce Xtreme Temperature Coating with lacquer thinner. Also remember to clean your spray gun immediately after using Xtreme Temperature Coating.

As with all KBS Products, multiple very thin, covering coats is always the best practice.


FOR BEST RESULTS, use natural bristle or foam/sponge brushes. Apply thin covering coats (1.5-2.0 mils/35-50um wet film thickness). Do not flood surface with coating.

Brush out thoroughly, maintaining a continuous wet edge and uniform appearing paint film. Do not over work brushing while attempting to eliminate brush marks. Whatever brush marks don't flow out during air dry process will flow out during initial heat curing. Do however avoid runs or drips.

Allow first coat to air dry at least 8 hrs before applying recommended second coat. Allow second coat to cure at least 8 hrs before subjecting to temperature curing.


For best results, apply when spray can and room temperatures are between 60-80° F (16-27° C). Shake can vigorously for one minute after mixing ball rattles freely & periodically during use to ensure proper mixing and to prevent spray head from clogging. Repeat shaking frequently during use.

Hold aerosol can 12-15 inches from surface and apply using steady, even strokes. Apply a minimum of two light coats, avoiding drips & runs. Allow 15-30 minutes drying time between coats. Heavy applications can lead to reduced coating life/adhesion. As with all KBS Products, multiple very thin, covering coats is always the best practice.

Clean spray head immediately after use by turning can upside down and spraying until no more paint appears. If clogging occurs, remove spray head and clean with a fine wire. Replace carefully, pointing can and spray head away from you.

Allow painted surface to dry a minimum of 8 hrs before subjecting to high heat.


After proper dry time, XTC will be dry to the touch and can be handled using care, but resins will not reach full hardness until heated to approximately 350° F (176° C) for 20-30 minutes. For headers or manifolds, this can be done in an oven, BBQ, or by mounting back on engine and run to normal operating temperature.

For automotive applications, you can also temperature cure by installing and running the engine. After the parts have been installed, start the engine and let it idle until the XTC begins to smoke then immediately shut engine off and let the manifold or header completely cool naturally to room temperature. Repeat and do this process three times total. After the third time, perform a fourth temperature cycling and on the fourth cycle, let the engine run until the XTC smokes and this time let the engine continue to run until the smoke from the XTC dissipates. Once the smoke has completely dissipated, turn the engine off let the surface come back to room temperature naturally. It is important to follow this process to gradually cure the XTC.

NOTE: Coating can emit potentially harmful vapors during the first few heat/cool cycles. Allow for full and proper ventilation during initial heat curing. Avoid excessive heat during this initial "break-in" period, as the resins need to be tempered into the substrate to provide proper adhesion.


XTC can be thinned up to 5% (20 parts paint/1 part thinner). Only thin using KBS #1 Thinner. Note: Use of other thinners not approved by KBS may hinder product performance and void product guarantee.


70°F (21°C) 50% RH. XTC will air dry tack and thumb print free within 1/2-1 hour. Allow at least 8 hours dry time between coats. Allow at least 8 hour solvent flash off period before heat curing or placing into service.

Optimum film properties require a heat cure of 350°F (176°C) for 20 minutes. Equipment such as exhaust manifolds & headers protected with the XTC in the air-dried state will heat cure when placed into service.


Thoroughly flush spray equipment and hoses immediately after use with KBS #1 Thinner or lacquer thinner. Dismantle spray equipment and clean parts, brushes or rollers.


Store in a cool, dry place with temperatures between 50°F and 100°F (10°C and 38°C). Keep container closed when not in use.


Q. Do I need to sandblast?
A. No, while a sandblasted surface is ideal for cleaning & providing an ideal anchor pattern or coating adhesion, wire brushing and/or abrasive sanding with 60-80 grit sandpaper will work well also.

Q. How many coats of XTC do I really need?
A. We recommend a minimum of two coats of Xtreme Temperature Coating or one coat of XTC Primer & one coat of XTC (color of your choice). Additional coats of XTC will just add to the durability.

Q. Do I need to heat the surface before painting?
A. No, the surface should be at room temperature 50-82°F(15-28°C) during application. Do not apply to a hot surface.

Q. Do I need to heat cure after application?
A. Yes, while the surface will dry to the touch within 1/2-1 hour, the coating will not reach it's full cure until it reaches approximately 350°F (176°C).

Q. Do I need to temperature cure between coats?
A. No, heat curing between coats is not necessary. In addition, heat curing will not hinder subsequent coats of XTC.

Q. If I temperature cured my piece already, can I apply another coat of XTC?
A. Heat curing will not hinder subsequent coats of XTC.
