ENVIROX SG – process<\/h1>\n

Chromium-free multifunctional corrosion protection for job coaters<\/p>\n

Alfipas 7816 – One product for three applications<\/h2>\n

The ENVIROX SG process is a chromium-free corrosion protection process that can be used for the pretreatment of steel and aluminium surfaces as well as for hot-dip galvanised substrates prior to powder coating. Alfipas 7816 is used here, which covers the treated metal surfaces with a firmly adhering, three-dimensional network (gel protective film) and thus offers excellent corrosion protection for final coating.<\/p>\n

Advantages:<\/h3>\n

Multifunctional application on Fe, Al and Zn<\/p>\n

Visible yellowish layer on Fe, colourless on Al and Zn<\/p>\n

Cost-effective integration into existing systems; suitable for evaporator technology<\/p>\n

Fully-fledged, sludge-free substitute for iron phosphating in steel pretreatment<\/p>\n

Approved for Al pretreatment according to Qualicoat (No. A-070) and GSB International (No. 303c)<\/p>\n

Analytical layer determination by quick test and quantitative, photometric measurement method<\/p>\n

Temperature-resistant layer up to at least 170 \u00b0C (annealing of Zn is possible)<\/p>\n

Simple waste water treatment by precipitation using lime milk<\/p>\n

Application and process sequence<\/h2>\n

Example of a process sequence for Al, Fe and Zn pretreatment with Alfipas 7816 in a plant (see right diagram).<\/strong><\/p>\n

Alfipas 7816 can be used both in spraying systems and in dipping processes. Rinse with deionised water before using Alfipas 7816. <\/p>\n

The process sequence and the type of pretreatment depend on the individual surfaces and the prevailing plant options. When pretreating aluminium and hot-dip galvanised surfaces we recommend an alkaline (etching and) degreasing followed by acid etching. In the case of mixed operations (Al +Zn), the zinc content in the acid etching bath should be carefully monitored. <\/p>\n

Steel substrates are also cleaned in the alkaline process bath (1st zone) before being rinsed and treated with Alfipas 7816.<\/p>\n

After the ENVIROX SG process, the fabric is again briefly sprayed with deionised water before being transferred to the dryer. <\/p>\n
