Coating to enhance the surface properties of glass fiber reinforced plastics

摘要

A laminate having enhanced surface properties is prepared by coating a fiber reinforced plastic (FRP) part with a sprayable, high solids, low volatiles coating. The coating comprises a first filler/glazing component formed from a mixture of a resin, a filler, a mixture of thixotropic clays, activated fumed silica, a phosphosilicate, and an organic solvent. The coating has a second catalyst component. The coating as applied to the FRP part has a thickness of up to 9 mils without sagging, running or cracking.
