ABSTRACT:
Liquid silicone compositions are described that cure to rubber which exhibits a unique combination of properties including low compression set and unprimed adhesion to a variety of substrates. The compositions include silicone polymers curable by hydrosilation reaction and specific combinations of adhesion promoting materials. Compositions containing aluminum chelates and epoxytrialkoxysilanes have been found particularly useful when adhesion to metal substrates is desired. When the compositions are desired to adhere to plastic materials, it is advantageous to include along with the aluminum chelate and epoxytrialkoxysilane, a tetraalkyltitanate, an alkylpolysilicate, and an acrylate or methacrylate compound.
