Taking many years for the development process pays off<\/p>\n
Development of the ENVIROX procedure already began in 1996. <\/p>\n
The first procedure designated ENVIROX A (Alfipas 740) on a silicate basis was already developed in 1997. However, due to usage being limited to dipping plants, this procedure was replaced in the same year by the ENVIROX S (Alfipas 745 – 746) that contains titanium. ENVIROX S can be used in dipping, spraying and flushing procedures. <\/p>\n
Due to many requests for a \u201cno-rinse\u201d procedure (\u201cwithout subsequent rinsing steps\u201d), the ENVRIOX NR (no-rinse; Alficoat 748 resp. 748\/3) was developed in 2000. Even today, this \u201cmillennium\u201d version is the most used chromium-free ENVIROX procedure for corrosion protection on aluminium surfaces prior to coating. <\/p>\n
An interesting development since 2010 has been the ENVIROX SG (Alfipas 7816), a procedure containing zirconium, which was developed especially for corrosion protection on iron\/steel surfaces. The procedure can also be used on aluminium and zinc surfaces and is therefore particularly interesting for job-coating companies that have to process different surfaces.<\/p>\n
1997 \u2013 ENVIROX S development was completed<\/p>\n
In 1998, a 1059 m\u00b2 company facade was pretreated with ENVIROX S as part of the GSB licence<\/p>\n
The first production-related use of ENVIROX NR abroad followed in 2000<\/p>\n
