A curable composition formed from: (A) a copolymer that has silicon-containing functional groups capable of crosslinking by forming siloxane bonds and molecular chain containing: (1) at least one monomeric unit selected from the group consisting of short chain alkyl acrylate esters and short chain alkyl methacrylate esters, said short chain alkyl groups having 1 to 8 carbon atoms, and (2) at least one monomeric unit selected from the group consisting of long chain alkyl acrylate esters and long chain alkyl methacrylate esters, said long chain alkyl groups having 10 to 30 carbon atoms; wherein the total amount of the monomeric units (1) and (2) in said copolymer is at least 50 weight %, and (B) an oxyalkylene polymer having silicon-containing functional groups that are capable of crosslinking by forming siloxane bonds; and (C) a curing accelerator, wherein copolymer (A) is present in an amount of 5 to 5,000 parts by weight per 100 parts by weight of oxyalkylene polymer (B), and curing acelerator is present in an amount of 0.1 to 20 parts by weight per 100 parts by weight of the sum of copolymer (A) and oxyalkylene polymer (B). |
