A composition for coating having an extensible property and outdoor durability of the coating layers under low temperature conditions is disclosed. The composition for coating comprises a fluorine-containing copolymer having hydroxyl groups, a polycaprolactone polyol or a polycarbonate diol, and a hardener having at least one functional group capable of reacting with a hydroxyl group. Coating layers formed by the composition have not only an extensible property under low temperature conditions, but also excellent outdoor durability and mechanical properties. The composition for coating and coating layers formed therefrom are suitable for fields in which excellent outdoor durability is a primary requirement, for example, bumpers, soft materials, and elastic materials such as internal parts for automobiles, and additionally, for concrete structures and mortar cement structures.
