Abstract

Organopolysiloxane compositions which are stabilized to heat and can be crosslinked to give elastomers, which as stabilizer combination contain (D) a copper compound in an amount from 1 to 180 ppm by weight calculated as elemental copper and (E) a zinc compound in an amount of from 1 to 180 ppm by weight calculated as elemental zinc, in each case based on the total weight of the organopolysiloxane composition which is stabilized to heat and can be crosslinked to give elastomers, and (F) optionally, organic fatty acid.
