Abstract
A moisture-curable polysiloxane composition consists essentially of (a) at least one polyorganosiloxane, fluorinated polyorganosiloxane, or combination thereof comprising reactive silane functionality comprising at least one hydrosilyl moiety; and (b) at least one base selected from amidines, guanidines, phosphazenes, proazaphosphatranes, and combinations thereof; wherein the curable composition is non-foaming and has an average condensation-curable, reactive silane functionality greater than two.
