Document Type and Number:
Japanese Patent JP6817289
Kind Code:
B2
Abstract:
A highly durable spring of the present invention includes a single-layer coating film with a thickness of 450 μm or less, in which the coating film contains an epoxy resin, a phenolic resin, and zinc. The coating film has high corrosion resistance and chipping resistance even if it is a one thin layer with a thickness of 450 μm or less. A method of coating a highly durable spring of the present invention includes an application process in which an epoxy resin-based powder coating material which contains an epoxy resin, a phenolic resin, and zinc and is produced by a melt kneading method is applied to a surface of a spring on which a coating-film is formed and a baking process in which the applied epoxy resin-based powder coating material is baked.
