Dust repellant compositions

Abstract

Sprayable, liquid polymeric film-forming compositions containing an amount of an anti-static polymer that is effective to provide films formed from the composition with resistance to the deposition of dust, soil or grime on the surface thereof, wherein the surface tension of the liquid composition is less than about 25 milli-newtons per meter. Methods for preventing the accumulation of dust, soil, or grime on surfaces such as a vehicle tire, wheel or wheel cover are also disclosed.
