Lightweight hardened protective coating and method for making and using same

摘要

An improved protective coating is disclosed that hardens to form a lightweight but extremely durable finish for a variety of substrates. The preferred coating comprises a mixture of lightweight comminuted porous expanded polytetrafluoroethylene (PTFE) particles suspended within a base paint mixture. When applied to and cured on a surface, the expanded PTFE particles form an interlocking grid network within the paint which is lightweight, durable, chemical and UV light resistant, and has a low coefficient of friction. The composition of the present invention is particularly suited for applications where a durable but lightweight coating is sought, such as in the aircraft industry.
