Processed metal plate for bonding non-condensable thermoplastic resin, surface-treated metal plate for bonding non-condensable thermoplastic resin, composite member, and method for producing a metal plate for bonding non-condensable thermoplastic resin

摘要

According to one aspect of the present invention, there is provided a chemical conversion coating comprising a metal substrate and a chemical conversion coating film provided on at least one side of the metal substrate, wherein the chemical conversion coating film contains an ethylene-acrylic acid copolymer, a colloidal silica and a silane coupling agent Acrylic acid copolymer is 10% by mass or more and the melt flow rate is 80 g / 10 min or less. The ethylene-acrylic acid copolymer is a non-condensation thermoplastic resin for use in the adhesion of a thermoplastic resin.
