、塗膜が剥離するおそれもある。そのために、金属の耐
食性が低下する。When this coated metal body is used for a long period of 31JJ under hot water or in the presence of an acid, cracks occur in the resin coating due to residual stress. There is also a risk that hot water or acid may enter the paint film, causing blisters or peeling of the paint film. Therefore, the corrosion resistance of the metal decreases.

しい。In order to solve these drawbacks, attempts have been made to add fillers to the coating resin constituting the coating film. The addition of suitable fillers reduces residual stresses and prevents cranking. To prevent blistering,
(i) Increase the elastic modulus of the coating film. (ii) Increasing the penetration path for hot water and acids by increasing the porosity of the coating film.
(iii) Increase the thermal conductivity of the coating film to reduce thermal diffusion. It is possible that In particular, thermal diffusion has a large contribution to the generation of blisters, and a method of increasing the thermal conductivity of the coating film is preferred.

の耐食性に優れた金属は高価である。The occurrence of blisters is not completely prevented. Although metal powder has high thermal conductivity, the resulting resin coating will rust because the metal powder itself lacks corrosion resistance. Metals with excellent corrosion resistance, such as nickel and titanium, are expensive.

して存用である。(Effects of the Invention) As described above, the coating resin composition of the present invention contains high-silicon cast iron powder, so when it is applied to metal, a coating film with excellent durability can be obtained. No blistering occurs when this coating is brought into contact with hot water. Moreover, the paint film will not rust. As a result, the composition of the present invention is useful as a coating resin composition for forming coating films on materials having heat resistance, corrosion resistance, and chemical resistance, such as pipes and containers for chemical plants.
