Chrome free passivation of aluminium and its alloys
Process (chrome free Conversion Coating for Aluminium Immersion Application) meets the requirements of RoHS, ELV and WEEE directives. It is used as an anti-corrosive film before dyeing (Class 1 of conversion coatings) and as an electrically conductive anticorrosive coating (Class 3).
Chemical steel passivation
The process is used to increase the corrosion resistance of ferritic, martensitic (AISI Type 4XX), austenitic (AISI Type 3XX) alloys and stainless steel with >17% of chromium or chromium and carbon content (Series 440).
