Abstract
A process for making a PVDF-based powder coating compositions using a co-coagulation process and compositions comprising co-coagulated PVDF, co-coagulated PVDF-based powder coating compositions and substances coated with these compositions. Vinylidene fluoride polymer latex compositions are mixed with compatible thermoplastic polymer latex, such as acrylic polymer latex, and a coagulant is added. The coagulant precipitates the vinylidene fluoride and polymer, and the precipitant is filtered and dried forming the powder coating. The powder coating is homogenous. The coating comprises no solvents and can be applied to a number of substrates.
