According to REACh European regulation, the use of substances like hexavalent chromium (recognized as a human carcinogen) or heavy metals will be banned at the latest in 2019 in Europe.
ArcelorMittal Europe – Flat Products develops its green technologies since 1995, and in 2011 its Granite® and Estetic® ranges of coated steels became Nature (see industry.arcelormittal.com/news/dec/Nature), free of chromates and heavy metals.
These technologies are now applied to Solano®, the leading coating for roof and wall cladding applications in demanding environments.
All the performances of the coated steel have been preserved, and even improved in some cases. Solano® Nature's phthalate-free, chromate-free and heavy metal-free paint system of 200μm, combined with a hot dip galvanized or galfan substrate, offers superior corrosion resistance even on cut edges (RC5 level) and an improved UV resistance (RUV3 classification, EN 10169/2 standard).
According to André Lavaud, product marketing manager, “Solano® Nature is the best environmentally-friendly choice to protect the envelopes of buildings erected in continental and oceanic Europe. It can be processed by bending, cold roll forming and deep drawing without damaging the surface. It can also be assembled with joining techniques such as clinching, riveting and adhesive bonding. The thermoplastic paints provide high surface robustness and ease of handling during envelope construction.”
With Solano® Nature, the whole range of ArcelorMittal Europe – Flat Products organic coated steels is now free of chromates and heavy metals.
