(57) [Summary] A cured product of a sealant such as a steel sheet or a silicone-based sealant, which is mainly composed of an organic polymer having at least one reactive silicon group, and has been subjected to acrylic electrodeposition coating, fluorine coating, or the like. Provided is a room temperature curable composition that exhibits sufficient adhesiveness. (A) 100 parts by mass of an organic polymer having a hydroxyl group or a hydrolyzable group bonded to a silicon atom and having at least one silicon-containing group capable of crosslinking by forming a siloxane bond; Epoxy resin 1 to 50 parts by mass, (C) oxazolidine compound 0.1 to 30 parts by mass, A room temperature curable composition containing (D) a silanol condensation catalyst and (E) an amine-based cocatalyst. |
