About Painted Sheet Metal

Hanging jig marks may be left when painting (see diagram on right).

The base coat of painted products is iron phosphate coating.

The main quality standards are shown in the table below.

The values are approximate values.

Powder Coating​ Painting
Film thickness *1
80±30μm
30±15μm
Baking temperature
180℃
140℃
Baking time
20 to 30 min.
Salt spray test *2
120 hours
72 hours
1: Not a guaranteed value as the coating thickness may vary depending on the shape. 2: Based on JIS Z2371 salt spray test method. (Powder coating: 60±5μm after baking at 180°C for 20 minutes, Painting: 25±5μm after baking at 100°C for 20 minutes)

We conduct confirmation using a film thickness gauge, peeling off with tape, and board test with a test piece.
The appearance is visually checked for color, dust, spots, dimples, etc., referring to the “Miscellaneous Materials Measurement Chart,” and the tapped holes are checked for functionality by passing bolts through them.

For cleaning, wipe with water or wipe with water after wiping with diluted neutral detergent using a soft cloth or sponge, and then wipe dry with dry cloth.

Please refrain from using petroleum solvents such as thinner, benzene, etc. and alcohol.
