Zusammenfassung:	A curable composition including (a) at least one organosiloxane compound, fluorinated organosiloxane compound, or combination thereof having reactive silane functionality including at least two hydroxysilyl moieties; (b) at least one organosiloxane oligomer, fluorinated organosiloxane oligomer, or combination thereof having reactive silane functionality including at least two hydrosilyl moieties; and (c) a catalyst composition including (1) at least one base selected from amidines, guanidines, phosphazenes, proazaphosphatranes, and combinations thereof, and (2) at least one Lewis acid. At least one of the components (a) and (b) has an average reactive silane functionality of at least three, and the composition is substantially free of organic solvent(s). An alkoxysilane compound may be optionally included in the curable composition. A process for coating the composition to prepare articles having the cross-linked composition on at least a portion of at least one major substrate surface is also disclosed.
