About Alufinish
Alufinish GmbH & Co. KG has been developing, producing and distributing chemical products for the surface pretreatment of metals since 1972. The portfolio covers the complete process chain for the anodizing of aluminium – from degreasing, pickling and chemical brightening through deoxidizing and sulfuric acid anodizing to electrolytic coloration and sealing – as well as pretreatment chemistry for iron/steel, hot-dip galvanizing and chromium-free multimetal passivation (Alfipas 7816 ENVIROX). The owner-managed company produces at its headquarters in Andernach and operates an application laboratory there for bath analysis, troubleshooting and custom formulations. With more than 500 customer services per month and sales partners in over 40 countries, Alufinish supplies anodizing plants, powder and contract coaters as well as the architecture and metal industries. Entry stages such as cleaning and pretreatment are approved according to Qualanod and Qualicoat and serve as preparation prior to painting, powder coating and anodic oxidation.
