ABSTRACT:
Room temperature stable organopolysiloxane compositions containing organosilicon compounds having Si-bonded hydrogen atoms and aliphatic multiple bonds, a platinum catalyst which promotes the addition of Si-bonded hydrogen atoms to the aliphatic multiple bonds and an inhibitior which prevents premature crosslinking at room temperature selected from the group consisting of a maleinimide and a maleic acid derivative of the formula ##STR1## where R.sup.1 is a hydroxyl group or a trimethylsiloxy group and R.sup.2 is a monovalent hydrocarbonoxy radical having from 1 to 20 carbon atoms per radical, which is bonded to the carbon atom of the ##STR2## group or a monovalent hydrocarbonoxy radical having from 1 to 20 carbon atoms per radical, which is bonded to the carbon atom of the ##STR3## group and which is substituted with at least one triorganosilyl group.
