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.
