Heat curable organopolysiloxane compositions.

摘要

Heat curable organopolysiloxane compositions are provided which utilize a vinyl containing polydiorganosiloxane, silicon hydride siloxane, a platinum group metal catalyst, and a triazoline dione as an inhibitor for the platinum group metal catalyst. The heat curable organopolysiloxane compositions of the present invention exhibit improved shelf stability, cure time and resistance to change in final properties when subjected to heat aging.
