ARTICLE PROVIDED WITH A NON-STICK COATING PROCESS FOR MANUFACTURE THEREOF AND COMPOSITION OF USE IN THE PROCESS

摘要

An article consists of a substrate whose surface has -OH groups, and of at least one non-stick polymer layer, which article also has applied between the substrate ant the non-stick polymer layer, a layer which is obtained by making an appropriate bifunctional organosilane react with a polyamic-acid precursor of polyamide-imide and with -OH groups of the substrate surface, then drying and converting said polyamic-acid into a polyamide-imide by heating at an appropriately high temperature. The article is particularly of cookware whose substrate is glass or glass-ceramic.
