Description: A dark brass/gold with a soft metallic finish.
Piston Coat is a thin film ceramic thermal barrier, designed to be applied on internal engine parts that require a thermal barrier.
Typical uses: piston tops, combustion chambers, valve tops, external turbo housings and exhaust components.
1 PINT COVERS ROUGHLY 50 SQUARE FEET.
CURE SCHEDULE:
TACK FREE AT 40 MINUTES
DRY AFTER 24 HOURS
FULLY CURED AFTER 5 DAYS
CAN WITHSTAND TEMPERATURES UP TO 2,000F+
SURFACE PREPARATION: All parts must be absolutely free of all oils, grease, moisture, dust, scale or corrosion.
METALS: For steel, sandblast with 80-100 grit aluminum oxide or similar. Softer metals, such as aluminum, use 100-120 grit aluminum oxide or similar at 35-40 PSI using a suction type blaster.
*NOTE: Phosphating may be preformed in lieu of sandblasting or in conjunction with the above mechanical etch.
FINAL CLEAN: Before spraying the part must be thoroughly cleaned using air blast, hot water rinse, solvent base rinse, or any other method that provides a clean dry surface. DO NOT USE petroleum based solvents,
MIXING: Stir and shake well, it is best to mix in a food blender type mixer or any unit capable of producing high speed shear/dispersion.
*NOTE: Use of non-distilled water may adversely affect product performance and void products warranty, whether express or implied.
PRIMER: No primer needed.
APPLICATION TEMPERATURES:
Material Surfaces Amblent Humidity
Normal 18-30ºC 18-30ºC 16-32ºC 65-85%
Minimum 13ºC 13ºC 10ºC 50%
Maximum 35ºC 38ºC 38ºC 95%
SPRAY: Apply coating in light fog passes (approximately 20% overlap) to achieve a thickness of .001” to .0015”. Use sufficient air volume for correct operation of equipment. (Minimum 50 PSI) Minimum part temperature should be 65f, if below warm up part. Spray at a right angle to part with a 1mm or smaller nozzle size. Spray all irregular surfaces and edges first, making an extra pass later. Check part for complete coverage.
SPRAY GUN & Mfr.: Any conventional unit. Recommended gravity feed type touch-up gun. (Important that nozzle size be 1mm or less) YOU ARE BEST TO USE A CHEAP HARBOR FREIGHT GUN, AND THROW IT AWAY WHEN DONE, AS THE CERAMICS EAT AWAY AT THE PARTS!
