Pre-treatment chemistry for iron, zinc and aluminium on a single line. Phosphating, chrome-free passivation, cleaning.
Chromium-free corrosion protection for job coaters, suitable for use on three different metal surfaces. Is that even possible? Yes, it is.
Phosphating is still regarded as the classic pretreatment of iron and steel surfaces before coating. We offer a wide range: classic iron phosphating or low-temperature products to efficiently reduce operating costs. Together with cleaning and passivation systems, the basis for good paint adhesion and protective function.
Hot-dip galvanising offers comprehensive corrosion protection that lasts for many years. Appropriate pre-treatment is required: our alkaline and acidic cleaning systems and special inhibitors ensure this. Duplex coating offers enhanced protection — but requires dedicated surface pre-treatment.
Pre-treatment processes applicable to a range of metal surfaces (Fe, Zn, Al), each with their own characteristic properties.
Iron phosphating — traditional pre-treatment for iron and steel surfaces. Already effective at low operating temperatures.
Pre- and post-treatment for hot-dip galvanising. Long-lasting corrosion protection down to the smallest corners.
No — we focus mainly on job coaters and aluminium-only pre-treatment.
Yes — please ask for the ENVIROX ZOX process (Alfipas 7840).

Yes — please ask for advice on the ENVIROX SG process (Alfipas 7816).

When the rinse bath foams, bath corrections are needed, or wastewater treatment is on the agenda — our specialty products have you covered.
Anodised façades should be cleaned regularly, and minor defects on anodised or powder-coated surfaces sometimes need touching up.

Alficolor PLR pens for touching up powder-coated surfaces
Good material fixation in pre-treatment depends on the right contact. Evaporation and energy loss during hot sealing can be reduced with a suitable cover.
Alongside expert advice and joint line planning with our customers, after-sales service is equally important.
