PROBLEM TO BE SOLVED: To obtain a room-temp.-curable compsn. improved in depth curability and adhesiveness by incorporating a polymer having hydrolyzable silicon groups and at least one cure catalyst selected from among tin compds. into the same. SOLUTION: This compsn. contains 100 pts.wt. polymer comprising a polymer (A) having hydrolyzable silicon groups represented by the formula: -SiXaR13-a and/or a polymer (B) having a polyoxyalkylene main chain, 0.01-10 pts.wt. at least one cure catalyst selected from among tin compds., and a filler, a plasticizer, etc. The tin compds. include a reaction product (K) of a dialkyltin oxide and an ester compd., a reaction product (K') of a dialkyltin oxide and a silicic ester, a reaction product (L) of a dialkyltin oxide, a carboxylic acid, and an alcohol, a reaction product (M) of reaction product K and a hydrolyzable-group- contg. silicon compd., a reaction product (N) of reaction product L and a hydrolyzable-group-contg. silicon compd., etc. In the formula, R1 is a 1-20C monovalent org. group; X is a hydroxyl or hydrolyzable group; and a is 1-3.
