    Abstract: There is provided a primer composition having a curative, a solvent, and an epoxide resin; wherein the curative is capable of reacting the epoxide resin; and further wherein; (a) the curative is capable of curing a perfluoroelastomer compound having at least one cure site and a crosslinking agent or catalyst; or (b) when the curative is not capable of curing the perfluoroelastomer compound, the perfluoroelastomer comprises a crosslinking agent or catalyst capable of curing the epoxide resin. The primer composition according to the present disclosure are used to bond perfluoroelastomer compounds to substrates. Methods of bonding a perfluoroelastomer compound to a substrate and multilayered articles comprising a perfluoroelastomer, a primer layer, and a substrate are also provided.

    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.
