SiSiB® PC9110 is a very unique silicone raw material useful in the synthesis or manufacturing of reactive silioxane polymers with random vinyl functionality the backone of the silicone polymer chain.

SiSiB® PC9110 may be used in formulating addition-curing silicone RTV or rubber formulations.

SiSiB® PC9110 is a very effective inhibitor for a platinum catalyzed addition-curing Two-Part RTV. When used as an inhibitor,

SiSiB® PC9110 is normally added to the crosslinker part of the formulation. Its high boiling point and low evaporation rate provides an extremely stable working time at ambient temperatures of the formulated Two-Part RTV.

SiSiB® siloxanes are widely used in cosmetics, deodorant, water repelling windshield coating, food additives and some soaps.
