Abstract
A non-stick coating formed on a substrate comprising a primer composition and a topcoat composition, wherein the primer composition is between the topcoat composition and substrate. The primer composition comprises at least one heat resistant adhesion promoter. The topcoat composition comprises at least one fluorocarbon resin and at least one heat resistant adhesion promoter other than a fluoropolymer that may be the same or different than the adhesion promoter of the primer composition. There are inorganic inert particles with an average particle size of at least about 10 micrometers contained in the primer composition. The invention includes the method for forming the coating.
