PAPRO Ecoat
Processing Overview
・This is a hexavalent chromium free environmentally friendly treatment for aluminum alloys.
The film is amorphous, which improves paint adhesion and corrosion resistance.
This system provides high aesthetics, corrosion resistance, paint adhesion, and hydrophilicity to aluminum and zinc alloys.
・In the past, surface treatments containing hexavalent chromium were used to improve the corrosion resistance of aluminum and zinc, etc.
However, the use of hexavalent chromium is restricted worldwide due to environmental problems.
PAPRO Ecoat is a hexavalent chromium-free treatment that improves corrosion resistance
The resulting coating is excellent in corrosion resistance and also has excellent performance as a paint pre-treatment.
