Abstract
The present invention is directed to curable compositions comprising: (a) a polyene; (b) a polythiol, present in an amount greater than 10 percent by weight based on the total weight of components (a) and (b) in the curable composition; and (c) a catalytic component consisting essentially of: (i) a metal compound; and (ii) a compound different from (i) that catalyzes an addition reaction between an ethylenically unsaturated compound and a thiol. The catalytic composition is essentially free of vanadium compounds. In the curable composition, either (1) both components (i) and (ii) of the catalytic composition (c) are added as a single package to (a) and/or (b); or (2) component (i) and/or (ii) of the catalytic composition (c) is added in separate packages to (a) and/or (b) of the curable composition. The present invention is further drawn to coated articles and methods of extending pot life of a curable composition.
