Organosilicon compositions which cure by way of a metal-catalyzed reaction of silicon-bonded hydroxyl radicals and/or silicon-bonded olefinic hydrocarbon radicals with silicon-bonded hydrogen atoms are stabilized for hours at room temperature by the incorporation of a hydrocarbonoxy-alkyl maleate. However, the stablized compositions are rapidly curable at low elevated temperature. Liquid organopolysiloxane compositions of this invention are particularly useful for coating operations, particularly paper coating operations to prepare an adhesive-releasing layer.
