NON-STICK COATING AND METHOD FOR PRODUCTION THEREOF

The invention relates to a non-stick coating for an article, having at least one bonding agent layer (V) applied to a surface of the article and a top layer (D), disposed over the bonding agent layer,wherein the bonding agent layer has a dry film layer thickness of 5 to 25 mum, and the top layer has a dry film layer thickness of 10 to 65 mum. In order to obtain an improved combination of non-stick effect and abrasion resistance, according to the invention the top layer contains 95 to 100 wgt.-% PTFE and, as applicable, up to 5 wgt.-% pigments, relative to the total solids content of the top layer, and is free of fluoropolymers which can be melt-processed, and the PTFE contained comprises between 100 wgt.-% of a high-molecular modified PTFE, which contains < 1 wgt.-% perfluoro propyl vinylether (PPVE) as a modified co-monomer and was obtained by emulsion polymerization. In a method for applying the non-stick coating, the bonding agent layer is applied in liquid form as a first aqueousdispersion to the surface
