Water-Based Cold Spray Zinc Coating
A water-based, low-VOC cold galvanizing coating with ≥ 92% zinc in the dry film, delivering 2,500+ hours of salt-spray protection. A cleaner, easier-to-apply alternative to hot-dip galvanizing and arc spray zinc for steel structures, bridges, power facilities and PV mounting systems.
≈ 39% better than hot-dip galvanizing (ISO 12944)
≈ 1.67× the durability of hot-dip galvanizing
Anti-corrosion performance still 82% after 2,500 h salt spray
