  • Patent number: 9303180
    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.
