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
Poor light resistance, not recommended for outdoor use.
