Abstract
A silicone rubber article (such as a wiper blade) has a low process fluid leach rate and high resiliency. The composition comprises, prior to cure, approximately 100 parts by weight of a vulcanizable elastomer including at least one silicone polymer, at least one crosslinkable process fluid, and low pressure and high pressure peroxide catalysts to accommodate a two-stage vulcanization process. According to the invention, the composition provides anti-hazing qualities and confers hydrophobic properties to a contacted surface. The polymer also includes about 50 to 220 parts by weight of a siliceous filler.
