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.
