RTV-2 Anti-Pollution Coating

YF Power provides RTV-2 silicone rubber anti-pollution coating which can significantly improve the operation safety of external insulation equipment for power transmission and transformation equipment. 


On the basis of summarizing and absorbing the application technology experience of anti-pollution flashover coatings at home and abroad, our company has developed a new type of anti-pollution flashover with better hydrophobicity, stronger arc resistance, higher mechanical strength and service life coating.


Our RTV-2 silicone rubber coatings create a hydrophobic surface that minimizes leakage current in the presence of moisture and contamination, reducing the risk of pollution-related flashovers. This ensures a long service life, prevents power outages, and protects electrical power equipment.


Contact us for more details about RTV-2 Silicone Rubber Coating, including TDS, application methods, OEM options, and more. We offer RTV coatings in various colors such as red, gray, white, and any other colors upon customer request.

Characteristics of RTV-2 Silicone Rubber Anti-Pollution Coating


  • The surface of the RTV-2 silicone rubber coating has excellent water repellency and fast, balanced and long-lasting water repellency.

  • The service life of the RTV coating product is longer and the technology is more advanced.

  • Ready to use, no need for thinning or excessive mixing/shaking before application, making it easy to use in various conditions

  • Perfect primer less adhesion.

  • Very good resistance to weathering - excellent hydrophobic properties.

  • Outstanding tracking resistance.

  • It is designed for easy cleaning. Facilitates cleaning in extreme pollution conditions (e.g., cement), with even the toughest contaminants easily wiped off.

  • Reduces maintenance and operational downtime, requiring less cleaning compared to traditional insulator surfaces.


Application of Anti-Pollution RTV-2 Silicone Rubber Coating


YF Power's Anti-Pollution RTV-2 Silicone Rubber Coating is a highly effective solution for enhancing the performance and longevity of electrical insulators and equipment in challenging environments. This advanced coating is specifically designed to protect against pollution-related flashovers and improve the reliability of power systems exposed to harsh conditions.


Key Applications:

  • Transmission Lines and Substations: Ideal for both new and aging insulators, including glass, porcelain, HTV silicone, and composite insulators. RTV-2 can be applied directly without primer, ensuring long-lasting protection.

  • Pollution-Prone Environments: Provides robust protection in environments exposed to salt spray, salt fog, industrial pollutants (e.g., cement dust, fly ash, acid emissions), and desert sand.

  • High-Voltage Systems: Suitable for AC and DC power systems across all voltage levels, including transmission lines, substations, railway systems, and switchgear.

  • Comprehensive Equipment Protection: Effectively shields various outdoor electrical equipment, including ceramic insulators, bushings, circuit breakers, transformers, hollow core insulators, and more.
