Waterborne Industrial Coatings for Metals - Long-Lasting Protection for Metal Surfaces
Product Overview
Waterborne Industrial Coatings for Metals represent a breakthrough in sustainable corrosion control, combining high-performance resin chemistry with ultra-low VOC (<50 g/L) formulations. Designed for steel, aluminum, galvanized substrates, and alloys, these coatings deliver ISO 12944 C5-M/CX-level protection through innovative hybrid technologies (acrylic-epoxy, polyurethane-siloxane). Certified to NORSOK M-501, ISO 20340, and SSPC-Paint 39 standards, they withstand salt spray exposure exceeding 3,000 hours while maintaining adhesion strength >8 MPa (ASTM D4541). Ideal for offshore, automotive, and infrastructure applications, this coating system reduces carbon footprint by 60% versus solvent-borne alternatives without compromising application efficiency or chemical resistance.
