Pinhole thickness

Pinholes are likely to occur when the coating thickness exceeds 150μm. Please notify in advance if the required coating thickness is greater than 150μm.

Salt spray resistance

GB1771-91

1000H

No change in the coating, corrosion at the cross-cut area is less than 2mm on one side. This test was conducted using chromated aluminum panels with a coating thickness of 100μm.

Humidity resistance

GB1740-79

1000H

Slight loss of gloss in the coating, less than Grade 1.

Light aging resistance

Good
