Article provided with a non-stick coating, with improved adhesion to the substrate and durability, its manufacturing process and composition used.

摘要

The invention relates to articles with a non-stick coating. It relates in particular to an article consisting of a substrate whose surface has -OH groups, and of at least one non-stick polymer layer, said article having also, applied between said substrate and said non-stick polymer layer, a layer which is obtained by making an appropriate bifunctional organosilane react with a polyamide-imide prepolymer precursor of a polyamideimide film and with -OH groups of the substrate surface, then drying and converting said polyamide-imide prepolymer into a polyamide-imide solid film by heating at an appropriately high temperature. Application in particular to production of cookware whose substrate is glass or glass-ceramic.
