  • Additive system to improve adhesion and hydrolytic stability of silicone elastomers
    Patent number: 6034174
    Abstract: An adhesion promoting method and a corresponding composition for improving the performance of silicone elastomers at high humidity are disclosed. The improved adhesion promoter comprises: (a) an epoxy functional silane; and (b) an acid. The acid may be phosphoric acid or any organic acid. Acetic and citric acids are preferred. The inclusion of the epoxy functional silane and acid in a standard silicone elastomer system provides greatly enhanced stability and adhesion under conditions of high humidity.
