What one part suffers greater duress and thermal shock than almost every other engine part combined? The Piston. That’s why we developed two distinctly different coatings to protect piston crown and side skirts from wear and damage.

We apply an incredibly durable Thermal Barrier Coating (TBC) to the combustion face of the piston, and a wettable Solid Dry Film (S01) to the skirt. The processes involve bonding particulates with an inorganic binder that is completely unaffected by petroleum products. With a bond strength of 10,000 psi, the coating's non-porous ceramic matrix results in improved flame travel and combustion efficiency, oil temperature is reduced and it prevents carbon buildup.

HPC's TBC prevents excessive heat from reaching the piston rings which results in less radial tension loss, less compression loss, and less oil consumption due to the rings overheating. TBC prevents heat losses through the piston, and cylinder temperatures are maintained. Because of this more horsepower is achieved due to increased fuel burn. We also protect the piston skirts via a Molybdenum Disulfide S01 coating designed to attract oil to ensure the piston skirt always maintains an adequate film of oil for reduced friction and scuffing. Motorcycles, snow mobiles, vintage cars, drag cars, Indy cars, trucks and compressors; it really doesn’t matter what the application, a coated piston delivers improved performance.

Valves like pistons also undertake greater thermal shock. Considerable research shows that an application of TBC to the combustion face of the valve prevents exhaust valve overheating, and intake tract heat transfer. The upshot is a denser air/fuel charge.

The second step in valve protection is the use of wettable S01 on the valve stems to reduce wear and horsepower losses due to friction. As is the case with piston skirts, the S01 provides incredible lubrication as well as attracting oil to insure life-giving lubricant film is always present.

Combustion chambers, inlet and exhaust port runners benefit greatly from TBC, in particular aluminium heads with a significant reduction in heat soak resulting in lower water temperature, and by retaining heat in the combustion chamber fuel burn is improved.
