Abstract

Abstract The invention provides a room-temperature-curing composition which comprises (A) a polymer ingredient comprising a copolymer (A1) which contains a silicon having a hydrolyzable functional group and has a molecular chain substantially comprising (a) alkyl (meth)acrylate monomer units having an alkyl group having 1 to 8 carbon atoms and (b) alkyl (meth)acrylate monomer units having an alkyl group having 10 to 30 carbon atoms, (B) a moisture curing catalyst, and (C) any of the following (C1) to (C3): (C1) a metal salt hydrate; (C2) a primary amine compound (C2a) and a compound having a carbonyl groups (C2b); and (C3) an inorganic filler surface-treated with a silicate. The room-temperature-curing composition of the invention is excellent in rapid curing property, depth curability, and workability.
