Application of Green Silicon Carbide in Coatings

Green silicon carbide (SiC) is a high-performance inorganic non-metallic material, characterized by high hardness, wear resistance, high-temperature resistance, and excellent chemical stability. Adding green silicon carbide to coatings can enhance their performance and expand their range of applications. Green silicon carbide has outstanding chemical stability, enabling it to resist erosion from acids, alkalis, salts, and other chemical substances. This enhances the corrosion resistance of the coating, protecting the substrate from corrosion. It is suitable for protective coatings in corrosive environments such as chemical equipment, marine engineering, and wastewater treatment facilities.

In high-temperature environments, coatings formulated with green silicon carbide can maintain a high level of chemical stability, preventing cracking or flaking of the coating under high temperatures. This makes it particularly suitable for protective coatings for high-temperature equipment, such as boilers, heat exchangers, and engine components. Simultaneously, green silicon carbide particles possess high strength and good toughness, which can enhance the mechanical properties of the coating. This improves the coating’s impact resistance and compressive strength, reducing the risk of damage due to external forces. It is ideal for applications requiring high mechanical strength, such as building structure coatings and bridge protective coatings.

When added to coatings, green silicon carbide can improve the thermal conductivity of the coating, helping it dissipate heat quickly. This is suitable for applications needing thermal performance, such as electronic device coatings and high-temperature equipment coatings. Moreover, this type of coating exhibits high reflectance and absorption rates for ultraviolet (UV) light, enhancing the coating’s UV resistance and preventing aging or fading due to UV exposure.

The rough surface of green silicon carbide particles increases the friction when added to coatings. This improves the slipping resistance, reducing the occurrence of slip accidents. It is suitable for floor coatings, ship deck coatings, and non-slip stair coatings. The role of green silicon carbide in coatings mainly lies in enhancing wear resistance, corrosion resistance, high-temperature resistance, mechanical strength, thermal conductivity, UV resistance, slip resistance, and optimizing rheological properties. By properly incorporating green silicon carbide, the overall performance of coatings can be significantly improved, meeting the demands of various application scenarios.
