Alficoat 748 (748/3) ( ENVIROX "NR" - Verfahren )

Product description

The ENVIROX "NR" process (product: Alficoat 748 or Alficoat 748/3, based on: titanium) is a chromium-free corrosion protection process for pretreating aluminium and aluminium alloys prior to powder coating. It is applied in suitable industrial plants. "NR" means "no-rinse", i.e. subsequent rinsing with water prior to the painting process is not absolutely necessary for the surface protected against corrosion in this way. Aluminium surfaces pretreated with Alficoat 748 (748/3) can be used in conjunction with suitable powder coatings for interior and exterior applications (e.g. for façade elements). The chrome-free product is approved for pretreatment in accordance with the specifications of the GSB - International and Qualicoat quality associations. The 10-year outdoor weathering test carried out by GSB International in Hoek van Holland was also successfully completed.
