    Abstract: The present invention provides for a substrate coated with a multi-layer non-stick coating which resists abrasion force and corrosion. The coating comprises a pre-primer base coat layer and at least two further coating layers, wherein at least two of said further coating layers comprise one or more fluoropolymer. The pre-primer base coat layer is substantially free of fluoropolymer, and comprises a heat resistant non-fluoropolymer polymer binder composition and inorganic filler particles, wherein greater than 50% of the inorganic filler particles are titanium dioxide, and wherein at least 10 weight % of said inorganic filler particles are large ceramic particles having an average particle size of at least 14 micrometers, and wherein some or all of the large ceramic particles extend from the pre-primer base coat layer at least into the next adjacent layer. The heat resistant non-fluoropolymer binder is preferably selected from the group consisting of polyimide (PI), polyamideimide (PAI), polyether sulfone (PES), polyphenylene sulfide (PPS) and a mixture thereof.

    Abstract: The present invention provides a process for improving the corrosion resistance of a non-stick coating on a substrate by applying a base coat to the substrate. The base coat comprises a liquid composition of heat resistant non-fluoropolymer binder and inorganic filler particles wherein the inorganic particles have an average particle size of no greater than about 2 micrometers. The liquid composition is applied to a substrate with a dry film thickness of at least about 10 micrometers, preferably about 10 to about 35 micrometers, and dried to obtain the base coat. A non-stick coating is applied over the base coat. The heat resistant non-fluoropolymer binder is preferably selected from the group consisting of polyimide (PI), polyamideimide (PAI), polyether sulfone (PES), polyphenylene sulfide (PPS) and a mixture thereof. More preferably the non-fluoropolymer binder comprises a polyamideimide having a number average molecular weight of at least about 15,000.
