Those having colloidal properties are suitable. Hydrous aluminum silicate is a highly purified sodium montmorillonite obtained through an extraction process from its natural swelling viscosity and is known as the main component of bentonite. Because it is an inorganic colloidal particle with a hydrating force, it swells significantly in water and forms a stable hydrogen colloid by dispersing, imparting Bingham plastic viscosity (thixotropy) to the formulation.

These phosphoric acid compounds can react with silicates at low temperatures (room temperature to 200° C.) to cure the coating and provide good adhesion to the substrate. Furthermore, since it has a cation exchange ability together with the above-mentioned hydrous aluminum silicate, it can form a complex with potassium ions, which are the cause of the efflorescence phenomenon observed in water glass paints.

A cross-cut was made on the painted surface of a test piece that was applied by spraying, dried, and heat-cured (0 x O, 8 mm) in accordance with JIS Z 2371, and after 96 hours, the degree of rust progression in the cross-cut portion was examined. . The evaluation criteria were that rust growth within 2111 points from the cross-cut portion was considered good, and when it was larger than that, it was considered poor.
■ 皮膜硬度。■ Film hardness.

。As explained above, the heat-resistant coating composition of the present invention can be applied at a relatively low temperature (200°C) and in a short time in a high temperature range (88°C).
Demonstrates excellent heat resistance and corrosion resistance up to 00℃),
In addition, it requires only a simple surface treatment from the perspective of the substrate, forms a strong film with good adhesion, and can be used in a wide range of industrial applications from the viewpoint of workability and energy saving.
このため特に、自動車エンジン廻りの防錆塗料として用
いることができる。Therefore, it can be used particularly as a rust-preventing paint for areas around automobile engines.
