Applications

Itis 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 effectivHydraulic Tool e 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.
