COATING COMPOSITION FOR CIVIL-ENGINEERING STRUCTURE MATERIAL, AND CIVIL-ENGINEERING STRUCTURE MATERIAL AND CIVIL-ENGINEERING STRUCTURE PREPARED BY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a coating compsn. excellent in adhesion to substrates by compounding (A) an air-dryable, polymerizable-monomer-crosslinkable unsatd. polymer which is an epoxyvinyl ester polymer formed by the vinyl modification of molecular terminals of an epoxy resin and (B) a polymerizable monomer component contg. at least one acrylic and/or methacrylic ester monomer. SOLUTION: Pref,, the air-dryable, polymerizable-monomer-crosslinkable unsatd. polymer has a double bond titer of 800-6,500 and contains allyl ether groups (CH2 =CH-CH2 -O-). Pref., the at least one acrylic and/or methacrylic ester monomer has a hydroxy group, contains an at least difunctional monomer, and gives a polymer or styrene copolymer having a glass transition temp. of 0 deg.C or lower. To increase the curability with the polymerizable monomer component, a paraffin and/or a wax may be used jointly.
