  • Resin compositions for coatings
    Patent number: 6274671
    Abstract: This invention relates to a coating resin composition including an acrylic resin (A) having a hydroxyl group and an alicyclic epoxy group attached to side chains thereof, an alicyclic epoxy resin (B) having an epoxy equivalent weight of 100-1000, an organoalkoxy silane compound (C) having a glycidyl group and a hydrolyzable alkoxy silane group contained in one molecule thereof, and an aluminum chelate compound (D). The composition is stably storable, highly curable at low temperature (80° C. or below) and capable of producing a highly weatherable coating, and is useful particularly as a coating resin composition of a one-pack type and a coating derivable therefrom. The composition also exhibits various superior coating performance characteristics (bonding, appearance, weathering resistance, chemical resistance, solvent resistance and the like) in a well-balanced state.
