Title: A COATING COMPOSITION, THE PREPARATION METHOD THEREFORE AND USE THEREOF
Abstract:
A waterborne polyvinylidene fluoride (PVDF) coating composition, the preparation method and use thereof are provided. The coating composition mainly comprises waterborne polyvinyl fluoride dispersion, a waterborne carboxyl acrylic resin, and a crosslinking agent. The coating gives excellent film performance which is comparative to that of solvent borne PVDF formulations. Meanwhile, the coating composition requires smaller amount of crosslinking agent in the formulation, and lower heating temperature for curing process, as compared with solvent borne PVDF formulations.
