Patent ID: 7807756

Claim:
A tin-free curable composition, comprising: (A) one or more organic polymers having a reactive-silicon-containing group, wherein a main chain skeleton of the one or more organic polymers is at least one polymer selected from the group consisting of polyoxyalkylene polymers, saturated hydrocarbon polymers, and (meth)acrylic acid ester polymers; and (B) a silanol condensation catalyst consisting of amine compound(s) (B1), wherein at least one part of the reactive-silicon-containing group(s) of the organic polymer(s) (A) is represented by the following general formula (I): —(CR 2 2 ) 2 —(SiR 1 2-a X a ) m —SiX 3 (1) wherein, R 1 s each independently represent a substituted or unsubstituted hydrocarbon group having 1 to 20 carbon atoms, or a triorganosiloxy group represented by (R′) 3 SiO—, wherein R's are each a substituted or unsubstituted hydrocarbon group having 1 to 20 carbon atoms, and R's, the number of which is 3, may be the same or different, R 2 s are each independently a hydrogen atom, or a substituted or unsubstituted hydrocarbon group having 1 to 10 carbon atoms, Xs are each independently a hydroxyl group, or a hydrolyzable group, a is 0, 1 or 2, and m is 0 or an integer of 1 to 19, and the composition contains the amine compound(s) (B1) as the silanol condensation catalyst (B) in an amount of 0.001 to 20 parts by weight for 100 parts by weight of the organic polymer(s) (A).
