For decades the yellow and green chromate was a reliable corrosion protection for aluminium surfaces, mainly as pretreatment for powder or liquid coating. As Chrom6 will be banned from production within the next years, ALBEA decided to replace yellow and green chromate against the well known system SURTEC 650, which has similar properties regarding corrosion protection. Furthermore ALBEA is offering the chromium-free system NABUTAN 310 before powder coating.
