ABSTRACT:
Addition curable silicone release compositions comprised of a vinyl-functional base polymer, a cross-linking agent, a precious metal catalyst, and an effective amount of C.sub.4 -C.sub.30 .alpha.-olefins are provided which allow reduction in the amount of catalyst or allow the use of vinyl-containing polymers having a lower degree of functionality. The compatibility of the .alpha.-olefin additives allow the preparation of a wide range of serviceable release coating compositions at reduced cost and improved efficiency.
