摘要
A process for making pigmented PVDF-based powder coatings by coagulation and powder based coatings made by the process. The process involves blending a PVDF latex and a water reducible acrylic polymer and pigment dispersion, adding coagulant to precipitate solid PVDF and pigment associated by ionic interaction with acrylic polymer binder, separating solids and drying the precipitate. Also, methods for coating substrates with the powder coating and coated substrates.
