Abstract
A curable coating composition comprising an ethylenically unsaturated organopolysiloxane base polymer, an organohydrogenpolysiloxane crosslinking agent, an effective amount of a precious metal containing hydrosilylation catalyst, and from 0.1 to 20 weight percent of a higher alkenyl-functional organopolysiloxane gum. The incorporation of the gum provides a composition which cures rapidly to a low coefficient of friction coating having stable release over time.
