USES APPLICATION

? In the synthesis manufacturing of reactive siloxane polymers with random vinyl functionality on the backbone of the silicone polymer chain.

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

? Very effective inhibitfa platinum catalyzed addition-curing two-part RTV. When used as an inhibitor, Vi-D4 is normally added to the crosslinker part of the formulation. Its high boiling point low evaporation rate provides extremely stable working time at ambient temperatures of the formulated two-part RTV.
