Abstract
A self-bonding solventless room temperature vulcanizable silicone rubber composition comprising a silanol polymer, a resinous copolymer composed of monofunctional siloxy units and tetrafunctional siloxy units, an alkyl silicate or partial hydrolysis products of an alkyl silicate as a cross linking agent which is pre-reacted with a tin salt of a carboxylic acid, and as a self-bonding additive, a nitrogen functional silane. This composition which can be made either clear or opaque is utilized with advantage for encapsulating photovoltaic cells and potting automotive electrical components.
