Abstract: The present invention is a room temperature curable resin composition comprising: as the main agent, an organic polymer in which both molecular chain terminals are sealed by a silanol group and/or a hydrolyzable silyl group; and an organic silicon compound of a specific structure having, in a molecule, an organosiloxane structure, a hydrolyzable silyl group, and a hindered amine skeleton. This resin composition produces a cured product in which the degradation over time associated with the effects of light such as UV rays can be suppressed.

Abstract: A coating composition comprising a hydrolyzable silyl-containing (meth)acrylic copolymer which is obtained from copolymerization of an alkyl (meth)acrylate with a silane compound having a long-chain alkylene linker between a hydrolyzable functional group and a radically polymerizable unsaturated group, and an organometallic catalyst is low-temperature curable and isocyanate-free. Even though the silane content is increased for coating hardness, the composition maintains alkali resistance and has good adhesion and solvent resistance when applied onto substrates.
