This invention provides a platinum-containing hydrosilylation catalyst in particulate form with an average particle size not exceeding 100 micrometers. The particles also contain a silicone resin having a softening point of from 50 to 200 degrees Centigrade. The improvement resides in the presence of a surface layer in said particles that is essentially free of the platinum-containing catalyst. As a consequence of this structure, when the catalyst composition is used as the curing catalyst in a hydrosilylation-curing organopolysiloxane composition, the composition characteristically exhibits an excellent storage stability while still curing rapidly upon heating.

Title
Method for preparing a particulate material comprising a platinum-containing hydrosilylation catalyst and a silicone resin.
