applications

it is used as a linear inhibitor in the formulating of two-part silicone rtv-2 addition curing systems.

because of the large vinyl content, small amounts are very effective in retarding and controlling the working time or pot life of two-part addition-curing silicone rtvs.

also, due to its boiling point of 139ºc, it is easily volatilized during curing. a suggested starting formulation is to use 0.25 to 0.50 parts by weight with 100 parts of the base polymer containing the platinum catalyst.
