ABSTRACT:
A process for improving the bath life and/or cure time of curable compositions. The process comprises first mixing an inhibitor with a catalyst, then adding that mixture to an organosilicon compound, and then adding the resulting mixture to an organohydrogensilicon compound. The process can optionally comprise a bath life extender compound. This process produces curable coating compositions which have a long bath life at room temperature and/or a rapid cure time at elevated temperatures such 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 immediately after being cured.
