In recent years, due to advances in powder coating technology, the usefulness of powder coatings has attracted attention. In particular, nylon powder coating has low water absorption, wear resistance,
It has characteristics such as excellent chemical resistance and coating processability, and is particularly used in the painting field for its functions such as corrosion resistance, electrical insulation, and abrasion resistance. . The conditions of use in these fields are extremely harsh, and the biggest problem is not only deterioration of the coating but also frequent peeling of the coating.

使用出来ない。 A compound obtained by polymerizing a diene compound has already been used as a primer for nylon resin powder coating. Also, Japanese Patent Publication No. 49-13094
Although the publication describes the use of a composition comprising an epoxy resin and an organosilicon compound as a primer for nylon resin, these primers cannot be said to have sufficient water resistance. Furthermore, it is necessary to preheat the primer, making it difficult to apply to coating methods such as electrostatic coating in which a coating film is formed by heating after powder coating. Epoxy resin is also used as a primer for electrostatic coating of nylon resin powder, but it also has poor water resistance and cannot be used for functional parts.

明を完成した。 As a result of studying various compounds to improve these points, the present inventor found that 50 to 80 parts by weight of epoxy resin and 50 to 80 parts by weight of phenol resin were used.
We have discovered that the water resistance of the coating film can be significantly improved by applying a composition consisting of 20 parts by weight or a condensate obtained by precondensation to an iron plate, and then applying nylon resin powder using an electrostatic coating method. The invention has been completed.
