A weather resistant coating composition comprising a miscible polymer blend of highly crystalline polyvinylidene fluoride polymer and polyalkyl methacrylate, such as PVDF and PMMA. The miscible blend comprises from about 50 weight percent to about 90 weight percent polymer comprising polyvinylidene fluoride and from about 10 weight percent to about 50 weight percent polyalkyl methacrylate. The polyalkyl methacrylate having a molecular weight within the range of about 25,000 grams per mole to about 200,000 grams per mole. The crystallinity of the polyvinylidene fluoride polymer is about 20% to about 70%. The weather resistant coating has excellent and unexpected physical characteristics, including solvent resistance and gloss retention.

Polyvinylidene fluoride weather resistant coating compositions including polymethyl methacrylate

A paint composition which comprises a binder component which includes a polyvinylidene fluoride polymer and a solvent component. The polyvinylidene fluoride polymer has a melt viscosity of at least 40 kPoise. Such paint compositions have low gloss and are useful as exterior weather-resistant paints for buildings where low-gloss paints are preferred.
