Alternative pre-treatment processes that are used in powder coating following pre-anodisation (e.g. as a special final rinse) must be approved by Qualicoat.

Alternative pre-treatment processes that are used in powder coating following pre-anodisation (e.g. as a special final rinse) must be approved by Qualicoat.

This test could already be successfully completed in the middle of last year with the new ENVIROX Preano – process (products: Alficoat 748 or Alficoat 748/3).

Now the official Qualicoat certificate is available. The products are given the approval number A-140 for this application area.

Both products can now be used for chromium-free pre-treatment before coating (ENVIROX NR) as well as for post-treatment of pre-anodised surfaces (ENVIROX PREANO) in Qualicoat member companies.
