CAL-30
Aluminum Trivalent Chromate Agent
CAL-30 is a trivalent chromate agent which can substitute hexavalent chromate agent. It is a high functional trivalent chromate agent which can be used in room temperature, and provides excellent corrosion resistance and adhesion on the surface.
[Features]
• Substitutes hexavalent chromate agent
• Provides corrosion resistance as same quality as hexavalent chromate agent
• Easy to handle in room temperature and by simple dipping
