Skirt and Top Coating:

PDM's Ceramic Piston Skirt Coating, is designed to be used, on any rigid or semi rigid surface experiencing sliding, rotating or oscillating friction. This coating will carry loads in excess of 350,000 PSI as well as lubricate at temperatures in excess of 1600f.

This coating combines the durability of a ceramic resin with the lubricity of the ceramic lubricant. It is used in applications where high temperatures, high loads and high speeds are experienced. When higher temperatures, than most other types of coatings can provide protection at, are experienced, this coating is fully capable of carrying the load.

Gray in color it acquires a glass like finish in use. Cured film thickness of .001 or less requires no change is piston clearance.

PDM's Thermal Barrier Coating for piston tops is designed for Performance engines running; Nitrous oxide, supercharged or Turbocharged. It creates a hard surface specifically designed for engines running High volumes of fuel and/or high compression ratios.

The thermal barrier coating. Reduces part temperature. Keeps heat in combustion chamber longer through the power stroke. Increase torque, H.P. and improved combustion chamber efficiency.
