  • Curable resin composition with improved adhesion of coatings
    Patent number: 5910555
    Abstract: A curable resin composition containing an oxyalkylene polymer having at least one silicon-containing reactive group in a molecule, and at least one compound selected from the group consisting of (1) a compound having at least one amino group and at least one trialkylsiloxy group in a molecule and (2) a silylamine derivative having at least one group with a hydroxy or hydrolyzable group bonded to the silicon atom and can be crosslinked through the formation of a siloxane bond, which provides a cured material having good adhesion properties with coatings and less residual tack.
