RAPID HYDROSILYLATION CURE COMPOSITION

A composition contains a blend of linear and resinous alkenyl functionalized polyorganosiloxanes, a blend of linear and resinous silyl hydride functionalized polyorganosiloxanes, and a hydrosilylation catalyst where the linear silyl hydride functionalized polyorganosiloxanes has a ratio of D/DH that...

More Information
Summary:A composition contains a blend of linear and resinous alkenyl functionalized polyorganosiloxanes, a blend of linear and resinous silyl hydride functionalized polyorganosiloxanes, and a hydrosilylation catalyst where the linear silyl hydride functionalized polyorganosiloxanes has a ratio of D/DH that is greater than 2.0 and less than 14, the molar and the ratio of silyl hydride hydrogens to the sum of terminal alkenyl functionality on the alkenyl functionalized polyorganosiloxane is 1.2-2.2.
