Abstract:
A spring with high durability has a coating film composed of an epoxy resin powder coating containing softening agent which contains an epoxy resin and a softening agent comprising a thermoplastic resin for improving impact resistance of the coating film. A method of coating a spring with high durability comprises a coating step of making an epoxy resin powder coating containing softening agent which contains an epoxy resin and a softening agent comprising a thermoplastic resin for improving impact resistance of a coating film adhere to a surface on which the coating film is formed, and a baking step of baking the epoxy resin powder coating containing softening agent adhered to the surface.
