Claims25
A silicone composition comprising a room-temperature vulcanizable adhesive formulation which comprises at least one bis(trialkoxysilylalkyl)hydromuconate.
A silicone composition comprising a room-temperature vulcanizable adhesive formulation which promotes adhesion to metal substrates, which composition comprises
- (F) at least one bis(trimethoxysilylpropyl)hydromuconate present in a range between about 0.1% by weight and about 5% by weight of the total composition;
- (G) a vinyl-containing polydiorganosiloxane present in a range between about 10% by weight and about 50% by weight of the total composition,
- (H) a hydrogen-containing polysiloxane in a range between about 1% by weight and about 15% by weight of the total composition,
- (I) a catalytic amount of a hydrosilylation catalyst,
- (J) an extending filler in a range between about 0% by weight and about 50% by weight of the total composition,
- (K) a reinforcing filler in a range between about 0% by weight and about 70% by weight of the total composition.
A method to provide cohesive failure to a silicone composition and metal substrate which comprises the steps of:
- (I) applying a silicone composition to a substrate wherein the silicone composition comprises at least one bis(trialkoxysilylalkyl)hydromuconate, and
- (II) curing the silicone composition.
A method to provide cohesive failure to a silicone composition and an aluminum clad substrate which comprises the steps of:
- (1) applying a silicone composition to a substrate to a thickness in a range between about 20 millimeters and about 60 millimeters, wherein the silicone composition comprises
- (I) bis(trimethoxysilylpropyl)hydromuconate present in a range between about 0.1% by weight and about 5% by weight of the total composition;
- (J) a vinyl-containing polydiorganosiloxane present in a range between about 10% by weight and about 50% by weight of the total composition,
- (K) a hydrogen-containing polysiloxane in a range between about 1% by weight and about 15% by weight of the total composition,
- (L) a catalytic amount of a hydrosilylation catalyst,
- (M) an extending filler in a range between about 0% by weight and about 50% by weight of the total composition,
- (N) a reinforcing filler in a range between about 0% by weight and about 70% by weight of the total composition, and
- (2) curing the silicone composition at a temperature in a range between about 25° C. and about 150° C. over a period in a range between about 0.25 hours and about 150 hours.
