Karstedt Catalyst is a high activity, high catalytic platinum catalyst. It is widely used in addition curing cross-linking reaction between Si-Vi and Si-H. The reaction can be catalyzed effectively and no side reaction. Betely’s platinum catalyst has high stability platinum formulation with low colour and turbidity. And it has high toxic resistance which reduce the influence of the poisons like amines, phosphines and sulfur compounds
