A curable organosilicon composition comprises a component having silicon-bonded hydrogen atoms, a component having silicon-bonded radicals reactive therewith, a curing catalyst, a catalyst-inhibitor and a bath life extender. The use of certain compounds, which are ineffective as a bath life extender in the absence of a catalyst inhibitor, effectively extend the room temperature bath life of a silicone coating composition containing a catalyst inhibitor. Being a substantial non-inhibitor for the catalyst the bath life extender component does not affect the cure time and/or cure temperature of the composition. This discovery has permitted the preparation of curable coating compositions which have a long bath life at room temperature and a rapid cure time at elevated temperatures which does not drift to longer intervals as the coating compositions ages over a typical production run. The room temperature cure times of the organo-polysiloxane coating compositions of this invention are adequately long and their cure times at elevated temperature are advantageously brief, so that they are useful in fast-paced coating operations, such as adhesive release coating operations wherein the cured coating is further coated with an adhesive in-line, i.e., immediately after being cured.
