ABSTRACT:
A method is provided for reducing the density of silicone foam from a platinum catalyzed foamable two-package mixture of vinyl organosiloxane, organohydrogen siloxane, and hydroxylated material. The platinum catalyst used in the foamable mixture is in the form of a mixture of a platinum vinyl siloxane and a platinum triarylphosphine. A platinum catalyst mixture of platinum vinylsiloxane and triarylphosphine also has been found effective.
