ABSTRACT:
Shelf stable heat curable mixtures of vinyl-substituted organopolysiloxane fluids and siloxanehydride are provided. These one part organopolysiloxane mixtures are catalyzed with an inclusion compound of a platinum metal complex, such as a complex of a platinum halide and 1,5-cyclooctadiene and a cyclodextrin.
