Abstract
Addition-curable platinum group metal catalyzed silicone compositions are provided which utilize a bis(trialkyloxysilyl)alpha-amino ester as an adhesion promoter. Cohesive bonding is effected on both plastic and metal substrates at temperatures of about 100.degree. C. in an hour or less.
Claims2
