Abstract
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.
Claims21
A paint composition comprising:
- (a) from about 30 wt. % to about 70 wt. %, based upon the weight of said paint composition, of a binder component, wherein said binder component comprises at least about 35 wt. %, based on the total weight of said binder component, of a polyvinylidene fluoride polymer having a melt viscosity of at least 40 kPoise, and from 0 wt. % to about 65 wt. %, based on the total weight of the binder component, of a polymer compatible with polyvinylidene fluoride;
- (b) from about 30 wt. % to about 70 wt. %, based on the weight of said paint composition, of a solvent component;
- and
- (c) a pigment, wherein said pigment is present in said composition at a pigment-to-binder weight ratio of from 0 to about 0.8.
A coated substrate, said substrate including at least one surface, wherein at least one surface of said substrate is coated with a paint including at least 35 wt. % of a polyvinylidene fluoride polymer having a melt viscosity of at least 40 kPoise.
