ABSTRACT:
The storage stability of catalyst compositions comprising a platinum-alkenylsiloxane complex, an organopolysiloxane, and a microparticulate hydrophilic silica is substantially increased when the pK.sub.a of a dispersion containing specified amounts of said complex and said silica in a non-polar solvent is at least 2.0. The silica is treated with an alkaline material to achieve said pH.sub.a value.
