Abstract:
1. Composition applicable for providing a non-stick abrasion-resistant coating on a surface, said composition comprising fluoropolymer and an effective amount of ceramic particles having an average size of at least about 10 micrometers to improve the abrasion resistance of said coating on said surface by at least 10% as determined by the dry SBAR method, said composition optionally containing adhesion promoter in an amount up to about 10 wt % of the wt. of said fluoropolymer, wherein the amount of said ceramic particles is from about 3 to about 40 wt % and the amount of said fluoropolymer is about 60-96 wt %, based on the combined weight of said ceramic particles and said fluoropolymer, said composition additionally containing 5 to 30 wt % of particles of inorganic film hardener having an average particle size of less than 5 micrometers based on the combined weight of said ceramic particles having an average size of at least 10 micrometer, said inorganic hardener having an average size of less than 5 micrometers, and said fluoropolymer, wherein said ceramic particles are SiC.
