HN-220 Weak Etching for Aluminum Alloy Wheel
Commodity Name
HN-220 Weak Etching for Aluminum Alloy Wheel
Composition and Working Conditions
HN-220 30~50 g/L
Temperature 20~50 ℃
Time 15~60 s
Application and Advantage
1. Remove oxide film and oil film from parts surface and form an even frosted layer on surface which helps
the subsequent process to form good adhesion.
2. Corroding speed is even, and wont appear partial corrosion. Especially suitable for light corrosion of
aluminum alloy wheel.
