ABSTRACT:
A process for preparing a one-component organopolysiloxane composition which comprises heating a catalyst which is capable of promoting the addition of silicon-bonded hydrogen to aliphatically unsaturated groups in the presence of an organopolysiloxane having aliphatically unsaturated groups and/or a filler at an elevated temperature and thereafter adding an organosilicon compound having silicon-bonded hydrogen to the mixture after it has cooled. The resultant composition, which can be stored at room temperature can be crosslinked by heating to a temperature of about 100.degree. C. or more.
