ABSTRACT:
A silicone rubber composition with a good shelf life and fast curing at elevated temperatures comprising a silanol end-stopped diorganopolysiloxane polymer, a silicone hydride and a rhodium complex catalyst in combination with an inhibitor compound selected from low molecular weight silanol end-stopped diorganopolysiloxanes, acetylenic compounds, olefinic carboxylic acid esters of aliphatic alcohols, alkenyl isocyanurates and mixtures of the above inhibitor compounds. The above compositions are especially suited as release coatings for plastic and cellulosic subtrates including paper.
