Abstract

Organopolysiloxane compositions which are stable on storage in the absence of moisture and can be crosslinked at room temperature on admission of moisture are based on organosilicon compounds containing at least two hydrolyzable groups, and contain, as catalyst, at least one titanium compound of the formulaTi(OR)4-n[(OR1)x—OR2]n  (I)whereR may be identical or different and are monovalent, substituted or unsubstituted hydrocarbon radicals,R1 may be identical or different and are divalent, substituted or unsubstituted hydrocarbon radicals,R2 may be identical or different and are as defined for R,n is 1, 2, 3 or 4 andx is an integer greater than or equal to 1.
