  • Method for forming multilayer coated film
    Patent number: 10717895
    Abstract: A method for forming a multilayer coated film on an electrodeposition-coated alloyed hot-dip galvanized steel plate include step (1) of applying an aqueous intermediate coating composition (X), step (2) of applying an aqueous base coating composition (Y), step (3) of applying a clear coating composition (Z) containing an epoxide, and step (4) of heat-curing each coated film. The coating composition (X) contains a hydroxyl group-containing acrylic resin (A), a polyurethane resin (B), a hydroxyl group-containing polyester resin (C), a melamine resin (D), and an active methylene-blocked polyisocyanate compound (E). The ratio of (A) to (B) is controlled to a specific range, and an elongation at break, Young's modulus and Tukon hardness of the coated film of the coating composition (X) are controlled to specific ranges.
