Abstract:
An improved process for manufacture of polymer coated composite substrates is described. a coated composite substrate is prepared in the press by applying a layer of a primer coating composition to the surface of a compressible mat comprising fibers and/or particles and a resin binder. The primer coating composition is formulated preferably as a fast setting polymer latex capable of forming a chemically crosslinked polymer matrix when applied to the surface of a compressible mat. a thermosetting top coat composition can be applied directly over the wet primer coating composition before heat-processing the mat to improve surface quality and release characteristics. Compressing and heating the coated mat produces a primed composite substrate directly out of the press.

Abstract:
A free-radical curable polish composition is described. The composition can be applied and cured as an ultra thin film on finished surfaces to provide enhanced chemical and mar resistance. The composition comprises an aqueous emulsion including an olefin-functional polymer or an olefin-functional prepolymer, and a silicone or silicone copolymer preferably with photoinitiators for UV and EB cure. The polish/emulsion can be applied, for example, to wet the surface of nitrocellulose lacquer wood finishes. The polish wet surface is first wiped to remove excess polish and thereafter exposed to UV radiation to provide a thin, polymerized protective film.

A free-radical polish composition is described. The composition can be applied and cured as an ultra thin film on finished surfaces to provide enhanced chemical and mar resistance. The composition comprises an aqueous emulsion including an olefin-functional polymer having low glass transition temperature or an olefin-functional prepolymer, and a silicone or silicone copolymer preferably with photoinitiators for UV and EB cure. The polish/emulsion can be applied, for example, to wet the surface of nitrocellulose lacquer wood finishes. The polish wet surface is first wiped to remove excess polish and thereafter exposed to UV radiation to provide a thin, polymerized permanent protective film on the polished surface.

Abstract:
A thermosetting, one package, waterborne coating composition comprising a hydroxy functional polymer and a tris(alkoxycarbonylamino) is described. The coating composition can optionally include carboxyl-functional resin components and can be clear or pigmented. Preferred embodiments of the present coating compositions include one or more catalysts selected from Brönsted or Lewis acids, tertiary amine bases, ammonium salts of Lewis acids, organo-tin compounds or metal chelating agents.
