SINOSIL-9120

SINOSIL™-9120 is a two-component, platinum-catalyzed, thermally conductive silicone rubber designed for electronic potting and encapsulation. It cures at room or elevated temperatures to form a soft, elastic, and electrically insulating elastomer. With excellent flowability and low hardness, it is ideal for protecting delicate components while ensuring effective heat dissipation.
