Wacker Group has formulated a tin-free catalyst for two-part, room temperature curing silicone rubber grades for moldmaking and encapsulation applications. Marketed as Elastosil Catalyst NEO, this catalyst has been specially tailored for use with the condensation-curing base components of Elastosil M rubber grades. Moldmaking compounds catalyzed with this product can be processed normally. They possess the same mechanical properties as traditionally cured compounds. Since its application is not subject to legal restrictions, Elastosil Catalyst NEO represents a practical alternative to conventional, tin-based catalysts.
