Detailed introduction
| Material Introduction | KED solvent-free heavy-duty anti-corrosion coating is a modified high-performance polymer anti-corrosion coating, designed with a special formula and integrating multiple cutting-edge technologies. This product has the characteristics of low water absorption, strong impermeability, excellent anti-corrosion performance, and salt spray resistance. It is sprayed and formed on site using specialized equipment and can meet most anti-corrosion environments. It is suitable for metal anti-corrosion applications immersed in seawater, sewage, acid alkali salt liquids, and can also be used in corrosive gas environments | |||
| Product advantages: | ||||
| Safety and Environmental Protection | Solvent free, high solid content, safe construction, environmentally friendly | |||
| Excellent anti-corrosion performance | The molded coating is dense, seamless, has good hydrolysis resistance, high electrical strength, and good insulation, which can effectively suppress the electrochemical corrosion of metals and withstand the erosion of highly corrosive media | |||
| Long anti-corrosion life | Not easily hydrolyzed, stable performance, fully ensuring that the coating is not easily damaged and guaranteeing anti-corrosion performance | |||
| High construction efficiency | Room temperature curing without heating | |||
