ABSTRACT:
A coated metal formed article includes: a metal formed article, a zinc-containing porous coating layer laminated on a surface of the metal formed article, a phenol-modified silicon compound layer laminated on the zinc-containing porous coating layer, and a fluorine resin-containing layer laminated on the phenol-modified silicon compound layer. The fluorine resin containing layer contains a fluorine resin and at least one organic resin selected from a polyester resin, a polyacryl resin, a polyolefin resin, a polyurethane resin, and a polycarbonate resin. An amount of the fluorine resin ranges from 1 to 200 parts by weight with respect to 100 parts by weight of the organic resin. When a thickness of the phenol-modified silicon compound layer is t2(μm) and a thickness of the fluorine resin-containing layer is t1(μm), a ratio of t1to t2ranges from 0.05 to 50 so that dimensional accuracy and mechanical properties are increased.
