Silane USi-O6414 is an essential coupling agent in industries as below:

Silane USi-O6414 is a very unique silicone raw material useful in the synthesis or manufacturing of reactive siloxane polymers with random vinyl functionality the backone of the silicone polymer chain.

May be used in formulating addition-curing silicone RTV or rubber formulations.

It is a very effective inhibitor for a platinum catalyzed addition-curing Two-Part RTV.

When used as an inhibitor, V4 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.



In 200L drum and 1000L IBC
