One-Step, Chromate-Free Anticorrosion Coating For Aluminum Alloys and Hot-Dip Galvanized Steel
Corrosion-resistant coatings. This technology provides high corrosion resistance and improved adhesion for hot-dip galvanized steel, aluminum alloys, and other metals in a one-step process without toxic chemicals like VOCs and Haps. Traditional anti-corrosion agents contain hexavalent chromium, which is toxic to humans and the environment, and contain high molecular weight polymers that require VOCs for anti-corrosion properties. VOCs are responsible for forming ground-level ozone and particulate matter and negatively impacting human health.
