Platinum hydrosilylation catalyst and method for making |
摘要 |
A method is provided for making a platinum hydrosilylation catalyst by equilibrating a mixture of an alkenylpolysiloxane and a cycloalkylpolysiloxane in the presence of a haloplatinic acid and thereafter treating the resulting equilibrate with a base. Improved rate of cure and a reduction in ppm levels of platinum required to effect hydrosilylation are achieved.
