The present invention relates to a low-temperature curable resin composition comprising a silyl group-containing polymer and an isocyanate compound, the main chain of which consists essentially of carbon-carbon bonds and which contains a hydrolyzable silyl group at the terminal or side chain. The present inventors have discovered that a polymer whose main chain consists essentially only of carbon-carbon bonds and which contains a silyl group having a hydrolyzable group at the terminal or side chain has a main chain consisting essentially of carbon-carbon bonds. In addition to the high gloss, weather resistance, and color fastness that are characteristic of ordinary vinyl resins, which are excellent as paints, coating agents, sealants, and adhesives, Improved adhesion to materials,
Furthermore, through room-temperature crosslinking with moisture, especially atmospheric moisture, a dense network structure is formed, resulting in solvent resistance, water resistance,
He discovered that this resin could be made into a resin with excellent heat resistance, high hardness, and weather resistance, and filed a patent application (Japanese Patent Laid-Open No. 54-36395). The present inventors further investigated silyl group-containing vinyl resins, and found that a resin composition consisting of a silyl group-containing vinyl resin and an isocyanate compound was easily cured not only at high temperatures but also at low temperatures. The present inventors have discovered that the excellent physical properties of vinyl resins can be further improved, resulting in a cured resin with particularly improved adhesion to organic substances and flexibility. That is, in the present invention, the main chain substantially consists of repeating carbon-carbon bonds, and at least one silicon atom in one molecule is bonded to a hydrolyzable group at the terminal or side chain.
The present invention relates to a resin composition comprising a silyl group-containing vinyl resin (A) and an isocyanate compound (B). The resin used in the present invention is made of a vinyl polymer whose main chain is substantially composed of carbon-carbon single bonds, and has at least one silicon atom bonded to a hydrolyzable group at the terminal or side chain in each molecule. silyl groups, preferably two or more, and most of the silyl groups are
