Chromate-free technology – DECORRDAL

Chromium (III) containing pretreatment systems such as DECORRDAL ZN 320 or DECORRDAL AL 325 are used for one, which offer advantages for the protection of blanks against corrosion in particular. Both are very solid in their application.

Secondly, chromium-free products are also used. These include DECORRDAL AL 230 A and DECORRDAL AL 240 A, which have been tried and tested for years and are certified by the GSB and QualiCoat quality associations.

Advantages

  • Equivalent replacement process for chromate systems
  • Permanent process quality monitored by quality associations
  • Excellent corrosion and adhesion results
  • Can be combined with many exterior paint systems (also highly weather resistant systems)
