Shaped and coated metallic material, composite, and method for manufacturing shaped and coated metallic material and composite

摘要

The present invention pertains to a shaped and coated metallic material used in a composite having excellent performance in bonding and sealing between a shaped metallic material and a molded article of a thermoplastic resin composition. The shaped and coated metallic material has: a shaped metallic material; and, disposed above the shaped metallic material, an acid-modified polypropylene layer containing at least 40 mass% of an acid-modified polypropylene. The melt viscosity of the acid-modified polypropylene layer is 1000 to 10,000 mPa·s. The film thickness of the acid-modified polypropylene layer is at least 0.2μm.
