Abstract
By curing either one of an organic peroxide-curable silicone rubber composition and an organic peroxide-curable unsaturated polyester resin composition and then curing the other composition while placing it in close contact with the cured composition, there is obtained a composite material in which an organic peroxide-cured silicone rubber is closely and firmly joined with an organic peroxide-cured unsaturated polyester resin.
Claims15
A composite material comprising an organic peroxide-cured silicone rubber part and an organic peroxide-cured unsaturated polyester resin part bonded together at an interface between the parts without the use of a primer between the parts.
A method for preparing a composite material comprising distinct parts of an organic peroxide-cured silicone rubber and an organic peroxide-cured unsaturated polyester resin which comprises:
- providing an organic peroxide-curable silicone rubber composition and an organic peroxide-curable unsaturated polyester resin composition,
- curing one of the organic peroxide-curable silicone rubber composition or organic peroxide-curable unsaturated polyester resin composition to obtain a first cured part,
- placing the other organic peroxide-curable silicone rubber or organic peroxide-curable unsaturated polyester resin composition in physical contact with the first cured part, creating an interface without intermixing of the first cured part and the other composition and without applying a primer between the first cured part and the other composition, and
- curing the other organic peroxide-curable silicone rubber or organic peroxide-curable unsaturated polyester resin composition, thus forming a bond at the interface between the parts.
