In recent year, the global encompasses of numerous environmental issues; and strict laws are increasingly being enacted to restrict toxic substances. Among others, the use of hexavalent chromium, a substance has been widely used as an effective coating for preventing rust, is likely to be restricted and phased out under the new environmental regulations adopted mainly in the U.S. and Europe. In respond to this trend, Winstar has recently developed the ZICOLLUM™ Coating system – an enhanced technology based on the traditional rust-preventive coating ruled for the past 30 years in the real world application.
Winstar ZICOLLUM™ is a Chromium-Free Zinc & Aluminum Coating system, which has the advantages of the traditional zinc & chromium coating system, but is completely FREE of chromium (neither HEXAVALENT nor TRIVALENT) throughout the entire process. The traditional zinc & chromium coating system is a water-based dispersant containing metallic aluminum, zinc flakes, chromic anhydride, glycol, etc.; while ZICOLLUM™ is a free of all dangerous substances, including nickel, cadmium, lead, barium and mercury.
Winstar ZICOLLUM™ Coating system includes three parts: ZICOLLUM™ Coating, ZICOLLUM™Sealer and ZICOLLUM™ Coating Techniques; which all comply with the recent environmental regulations and are therefore the perfect substitution of the traditional zinc & chromium coating system.
