ABSTRACT:
A windshield wiper imparting hydrophobic properties to a surface over which it moves is prepared from a polymerized silicone elastomer having about 3 to 20 parts per hundred of a dispersed filler selected from silica, mica, molybdenum disulfide, and tetra fluoro ethylene, and about 0.2 to 10 parts per hundred of an additive of dicoco dimethyl ammoniumchloride or an acetate salt of a copolymer with the formula ##EQU1## and X has a total value of from 10 to 400 inclusive. Also disclosed is a method of imparting repellency to a windshield by immersing a wiper in an alcohol solution containing about 50 weight percent of the acetate salt of the copolymer named above.
