Application
(1) Be primarily used as an end-capper in the production of vinyl end-capped siloxane polymers. The vinyl end-capped silicone polymers can be used in a wide variety of end use applications such as silicone rubber, sealants, coatings and cosmetics.
(2) Be used as a linear inhibitor in the formulating of two-part Silicone RTV-2 Addition Curing systems.
(3) 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 RTV rubber silicones.
(4) 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 of SiSiB® PC9401 with 100 parts of the Base polymer containing the platinum catalyst.
Packaging and Storage
Packaged in 160Kg steel drums.
In the unopened original container, store in a dry and cool place, the shelf life is one year.
