Learn about the characteristics of heavy coatings and the importance of their application

Thread Content

Heavy anti-corrosion coating refers to a specialized coating technology that uses highly corrosion-resistant coatings with a film thickness of 200–300 μm or more, enabling an anti-corrosion lifespan of 10–50 years in harsh corrosive environments. Due to its particularly long corrosion resistance period, it is also known as a long-lasting anti-corrosion coating. A notable feature of heavy anti-corrosion coatings is their thick film structure. To achieve decades of corrosion resistance, a thin coating is not effective. The development of highly corrosion-resistant resins and new pigments and fillers is a prerequisite for achieving heavy-duty anti-corrosion coatings. Thorough surface cleaning of the metal substrate is the foundation for heavy-duty anti-corrosion coating. Scientific coating design requirements, coating systems, and coating application techniques are key to achieving high-level corrosion resistance in coatings; strict quality inspection and maintenance management are essential to ensure such corrosion-resistant results.
