<p>A platinum catalyzed silicone rubber composition with an improved work life having as its base constituents 100 parts of a vinyl-containing polysiloxane where the vinyl concentration is at least 0.005 mole percent, at least 0.1 parts per million of a platinum catalyst and from 1 to 50 parts based on 100 parts of the vinyl-containing polysiloxane of a hydrogen-containing polysiloxane and further having as an inhibitor additive a compound with at least one radical of the formula, - C - O - O - H The preferred inhibitor compounds containing the hydroperoxy radical are tertiary butyl hydroperoxide, methylethylketone hydroperoxide, cumene hydroperoxide, 1,1,3,3-tetramethylbutyl hydroperoxide and 2,5-dimethyl-2,5-dihydroperoxyhexane. The silicone rubber composition is generally referred to as a room temperature silicone rubber. Once the silicone rubber composition cures it is quite useful as a water sealant.</p> |
