Abstract: The invention relates to a high shear stable aqueous fluoropolymer coating composition, preferably using polyvinylidene fluoride (PVDF), such as KYNAR® PVDF, suitable for high performance coating applications. The composition is based on a high shear stable fluoropolymer emulsion having small particle size, blended with an acrylic polymer additive. The use of this composition allows high bake PVDF water-base coatings which can be applied on variety of substrates such as metal or ceramic surfaces, and in the impregnation of textiles, glass, carbon or aramid fibers, etc. The dry coating formed from the coating composition of the invention exhibits improved gloss, crack resistance, chemical resistance, hot dirt pick up resistance and other improved properties.

Abstract: The invention relates to an process for coating a glass substrate with an environmentally friendly aqueous, fluoropolymer coating composition. The process involves applying a polyurethane primer to the glass substrate, and partially, but not completely crosslinking this primer coating. An aqueous hydroxyl-functional fluoropolymer coating is then applied to the partially crosslinked primer coating, and the coating allowed to fully cure. The invention also relates to the intertwined multilayer primer/fluoropolymer coating on the glass substrate. The final coating has excellent wet adhesion to glass, good weathering, durability, chalking resistance, chemical resistance, and dirt pickup resistance.

Abstract: The invention relates to a polyvinylidene fluoride (PVDF) solvent dispersion composition containing PVDF (such as KYNAR 500) that is free of fluorosurfactants, an organic solvent, and low levels of dispersants. A pigmented version of this dispersion is also covered. The dispersion is useful for producing tough, chemical-resistant coatings, especially on metallic substrates, including for use as a coil coating or an architectural coating.
