Abstract: A coating composition containing a film-forming organosilane polymer and a sterically dispersed macromolecular polymer having silane functional macromonomer chains which react with the silane functionality of the organosilane polymer. The coating composition can be used as the clearcoat over a conventional pigmented basecoat, or as a basecoat or monocoat or primer when a suitable amount of pigment is incorporated therein. The coating composition provides improved chemical resistance and is not prone to cracking.

Abstract: A coating composition containing a film-forming organosilane polymer and a sterically dispersed polymer having macromonomer chains which react with the silane functionality of the organosilane polymer. Silane functionalities in the core of the dispersed polymer provides post-cure crosslinking in the core. The coating composition can be used as the clearcoat over a conventional pigmented basecoat, or as a basecoat or monocoat or primer when a suitable amount of pigment is incorporated therein. The coating composition provides improved chemical resistance and is not prone to cracking.

Abstract: Zeolites, including ultramarine blue retard the oxidative degradation of melt processible perfluorocarbon resins including FEP and PFA at elevated temperatures. Coating compositions of the perfluorocarbon resin, zeolite, and iron-containing pigments are provided.

Abstract: A multilayer coated article such as a baking pan with a primer of silicone resin and silicone oil and a topcoat of silicone resin, colloidal silica and flake pigment.

Abstract: Zeolites, including ultramarine blue, retard the oxidative degradation of polytetrafluoroethylene resin (PTFE) at elevated temperatures. Coating compositions of PTFE, zeolites, acrylic resin and iron-containing pigments are provided.

Abstract: A non-stick coated steel article, such as cookware, has a coating of a ceramic frit in two parts, first a non-porous layer, then a porous layer, overlaid with a fluorocarbon primer and, optionally, a fluorocarbon topcoat.
