ABSTRACT:
Catalyst compositions suitable for use in one-part storage stable organosiloxane compositions that cure by a platinum-catalyzed hydrosilation reaction are prepared by blending a liquid complex of a platinum group metal compound and an ethylenically unsaturated organosiloxane compound with an alkylenediamine, and then combining the resultant mixture with an acetylenic alcohol. The catalyst compositions also contain at least one organohydrogensiloxane that is present prior to or during blending of said alkylene diamine with said acetylenic alcohol.
