| Application | 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 139c, it is easily volatilized during curing. A suggested starting formulation is to use 0.25 to 0.50 parts by weight of USi-O6214 with 100 parts of the Base polymer containing the platinum catalyst. |
