Aluminum wheel coating

Function positioning:

Surface treatment of passenger car aluminum wheels before powder coating

Application scenario:

Parts aluminum wheel manufacturing plant

Application substrate:

aluminum

Value advantage:

Significantly improve the bonding force and corrosion resistance of aluminum parts after powder spraying;

Damp heat test:

No obvious blisters after 96 hours at 37°C-100% relative humidity;

Salt spray experiment:

5% salt solution 35 ℃ 1000 hours test unilateral corrosion can not be greater than 3mm without obvious blisters;

CASS Karnofsky test:

5% salt solution plus copper chloride and acetic acid for 168 hours in the experiment, the unilateral corrosion should not be greater than 3mm without obvious blisters;

Fibrous corrosion test:

6-hour Karnofsky test (45 degree angle, 2-3 seconds water washing) 672-hour damp heat test (60°C 85% relative humidity) to measure the maximum fibrous corrosion length every week (scratch spacing of 40 mm can not be greater than 4 mm after standardization) Currently in the United States The laboratory calibration factor is 1.2)
