The compression set of elastomeric silicone compositions, addition cured injection moldable compositions or millable compositions, is reduced by the incorporation of nitrogen compounds wherein the nitrogen possesses at least one organic substituent and the nitrogen is tetravalent wherein the nitrogen is cationic. The adhesion of such compositions to thermoset or thermoplastic polymer substrates is improved by the addition of bis(trimethoxysilylpropyl)fumarate and a disilanol that may or may not contain alkenyl groups.
