ABSTRACT:
A coating composition for application to a metal part, which improves corrosion resistance and significantly reduces the co-efficient of friction of the surface of the part and a one coating step method for applying the coating to form two distinct layers on the coated part. The composition includes an oil phase in which polytetrafluoroethelene particles are suspended mixed with a resin film forming paint composition. Upon applying the coating to the part and curing of the resin film, the oil phase separates and forms a overlayer of oil having the polytetrafluoroethelene particles uniformly distributed in the oil layer.
