ABSTRACT:
Polyorganosiloxane gels exhibiting a resistance to discoloration, hardening and surface deformation at temperatures of 100.degree. C. and above can be prepared by curing compositions comprising a polydiorganosiloxane containing silicon bonded fluorinated hydrocarbon radicals and an organohydrogensiloxane containing at least three silicon bonded hydrogen atoms per molecule in the presence of a platinum containing catalyst and up to 0.1 percent, based on the weight of said composition, of copper acetylacetonate.
