Applications

Silane OSi HIOSil 6509 is used as a linear inhibitor in the formulation 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 139 ºC, it is easily volatilized during curing.
