Solid compositions for spraying the coating of metal substrates, a method for spraying the coating of a metal substrate and a metal object are presented. The coating spray mixture is a thermoplastic substance and consists of: (a) a polyester with an average molecular weight of 10,000 to 50,000, but also (b) a resin selected from epoxy resins having an epoxy equivalent weight of 5,000 to 15,000, acrylic resins or polyolefin resins . The coating spray mixture is applied to the metal substrate in the spraying process and forms a mixture layer with a thickness of about 1 to about 40 microns. |
