Abstract

A curable composition comprises (a) at least one inorganic or organic compound comprising reactive silane functionality comprising at least one hydrosilyl moiety; (b) at least one inorganic or organic compound comprising reactive silane functionality comprising at least one hydroxysilyl moiety, the hydroxysilyl moiety optionally being generated in situ by hydrolysis of at least one hydrosilyl moiety; and (c) at least one base selected from amidines, guanidines, phosphazenes, proazaphosphatranes, and combinations thereof; with the proviso that, when component (a) is an organic polymer, then component (b) is different from component (a) and is not generated in situ by hydrolysis of component (a).
