COMPOSITIONS DE POLYORGANOSILOXANE VULCANISABLES A TEMPERATURE AMBIANTE A STABILITE DE CONSERVATION AMELIOREE

摘要

Room temperature vulcanizable organopolysiloxane compositions are provided which exhibit improved stability and a reduced tendency to corrode copper upon contact resulting from the employment of an effective amount of a tin condensation catalyst having organo radicals attached to tin by carbon tin linkages and whose remaining valences are satisfied by a chelate radical or a dicarboxylate radical in combination with an organic triazole such as benzotriazole.
