For engine rotors, we offer a two step coating process. The first is a thermal barrier coating applied to the rotor faces. This thermal barrier coating is a polymer composite with insulating ceramics designed to significantly reduce heat transfer and saturation. This coating lowers your engine's oil temperature and increases thermal efficiency. Keeping oil temperatures under control is critical in high output and racing engines.
The second step is a lubricant retention coating. This dry-film application mimics the OEM factory coating located on the oil lands of the rotor. Our lubricant retention coating is specifically designed to retain engine oil on critical component surfaces during intense heat and extreme pressures. Running clearances between the rotor housings and rotors are very minimal, usually within .011". Under higher power outputs and RPMs, the chances of rotor tip deflection damaging the side irons is increased. This coating helps aid in preventing this contact.
These coatings will create a .0002" to .0007" overbuild on the component surface, but will have an actual penetration depth of approx. .005" to .50" depending on material applied.
Coatings are designed to be flexible enough to allow for expansion and movement.
These coatings are designed to last nearly indefinitely.
Rotors are required up front for service.
