NOVELTY - A coating composition comprises a powder mixture comprising 0.8 wt.% zinc, 0.06-0.11 wt.% phosphorus and the remainder of aluminum, 0.01-0.4 pts. wt. graphene oxide with respect to 100 pts. wt. of the powder mixture, and an adhesive resin in which the powder mixture is uniformly dispersed. The adhesive resin comprises 0.1-0.2 pt. wt. 2-(1E)-2-(2,3-dihydro-1,3-benzothiazol-2-yl)hydrazin-1-ylidenemethyl-4-{(2E)-3-phenylprop-2-enoyloxy}phenyl (2E)-3-phenylprop-2-enoate compound (I), 0.1-0.2 pt. wt. 2-(1E)-(2E)-2-{4-(2-fluoro-4-propylphenyl)phenylmethylidene}hydrazin-1-ylidenemethyl-4-({4-3-(prop-2-enoyloxy)propoxycyclohexyl}carbonyloxy)phenyl 4-3-(prop-2-enoyloxy)propoxycyclohexane-1-carboxylate compound (II), and 0.1-0.2 pt. wt. (2Z)-2-(4-butoxyphenyl)-3-(2-{2-4-(diethylamino)phenylhydrazin-1-yl}-hexahydrothieno2,3-d1,3thiazol-5-yl)prop-2-enenitrile compound (III) with respect to 100 pts. wt. of the powder mixture. USE - Coating composition used for bonding film (claimed) and steel structure or concrete structure. ADVANTAGE - The coating composition provides film having excellent corrosion resistance, physical property, waterproof property and anticorrosive property, and increased the durability of steel structure or concrete structure. DETAILED DESCRIPTION - A coating composition comprises a powder mixture comprising 0.8 wt.% zinc, 0.06-0.11 wt.% phosphorus and the remainder of aluminum, 0.01-0.4 pts. wt. graphene oxide with respect to 100 pts. wt. of the powder mixture, and an adhesive resin in which the powder mixture is uniformly dispersed. The adhesive resin comprises 0.1-0.2 pt. wt. 2-(1E)-2-(2,3-dihydro-1,3-benzothiazol-2-yl)hydrazin-1-ylidenemethyl-4-{(2E)-3-phenylprop-2-enoyloxy}phenyl (2E)-3-phenylprop-2-enoate compound of formula (I), 0.1-0.2 pt. wt. 2-(1E)-(2E)-2-{4-(2-fluoro-4-propylphenyl)phenylmethylidene}hydrazin-1-ylidenemethyl-4-({4-3-(prop-2-enoyloxy)propoxycyclohexyl}carbonyloxy)phenyl 4-3-(prop-2-enoyloxy)propoxycyclohexane-1-carboxylate compound of formula (II), and 0.1-0.2 pt. wt. (2Z)-2-(4-butoxyphenyl)-3-(2-{2-4-(diethylamino)phenylhydrazin-1-yl}-hexahydrothieno2,3-d1,3thiazol-5-yl)prop-2-enenitrile of formula (III) with respect to 100 pts. wt. of the powder mixture. An INDEPENDENT CLAIM is included for a bonding film, which involves (a) preparing the powder mixture and (b) preparing the adhesive resin, mixing a composite adhesive resin and spraying it on the surface of the structure.
