ABSTRACT:
Polyorganosiloxane rubber compositions which cure to elastomers under the influence of heat comprise 0.01 to 1 part by weight of ammonium, alkali metal or alkaline earth metal carbamate. The green strength of the rubber compositions is increased by the addition of carbamate. At the same time, the compression set of the vulcanized rubbers are reduced.
