Characteristics:
It can be used for aluminum and aluminum alloy workpiece.
It can be used to obtain uniform colorless and transparent chemical conversion film on aluminum and aluminum alloy workpieces (passivation film weight is about 0.2g/M2). It has excellent anti-corrosion properties and decorative properties with excellent anti-color change ability;
Chromium-free passivate is a colorless and transparent liquid composed of zirconium and titanium metal ions, film-forming promoters, stabilizers and PH adjusters. It does not contain heavy metals chromium, lead, cadmium and other harmful organic substances. Specific gravity: 1.03-1.04, PH value: 2.0-3.0, it is an environmentally friendly new product;
The chemical conversion film is firmly bonded, which can significantly enhance the bonding of the workpiece with the coating and paint;
Working at room temperature or low temperature, the tank liquid is simple to detect, easy to operate and manage. Simple method of tank solution preparation, stable performance and long service life;
Bare passivation film resistance to neutral salt spray test can reach more than 400h.
