    Abstract: The invention features a coating composition that comprises a non-urethane acrylate or methacrylate compound in combination with a fluorochemical. Typically, the non-urethane (meth)acrylate is an aliphatic or aromatic (meth)acrylate compound and the fluorochemical typically comprises a monofunctional (per)fluoropolyether (meth)acrylate compound. The coating compositions can provide a protective topcoat layer to a variety of substrates, including wood and vinyl.

    Abstract: A fluoropolymer coating composition contains a homogeneous mixture of crystalline submicron fluoropolymer particles dispersed in a solvent-borne solution of less crystalline or amorphous fluororesin. The composition may be prepared by blending a latex containing crystalline submicron fluoropolymer particles with a latex containing less crystalline or amorphous fluororesin particles, coagulating and drying the blended latices, and dissolving the dried blend in a solvent for the fluororesin particles. Quasi-homogenous compositions may be prepared by blending dry crystalline submicron fluoropolymer particles with a) dry less crystalline or amorphous fluororesin particles and a solvent for the fluororesin particles, or b) a solvent-borne solution of less crystalline or amorphous fluororesin. Rubbing the disclosed coatings can provide a thin, continuous or nearly continuous fluoropolymer surface layer atop a less crystalline or amorphous fluororesin binder containing crystalline submicron fluoropolymer particles.
