Room Temperature Vulcanized Silicone Rubber anti-pollution coating, abbreviated as RTV coating, has rapidly developed and been widely applied as a new technology and material in China since 2000 due to its long-lasting, maintenance-free advantages. They are primarily used for preventing pollution flashovers on the external insulation of insulators or electrical equipment in power systems.
The main components of RTV silicone rubber coating include trichloroethylene, tetrachloroethylene, KX organic composite solvents, and KX-240H.
YF Power, as a professional manufacturer and supplier of RTV coating for insulators, produces different types of RTV insulator coating, including RTV Anti-Pollution Coating and PRTV High-Self Cleaning Anti-Pollution Coating.
The hydrophobicity and hydrophobic migration of the coating are key factors in significantly increasing the pollution flashover voltage level.
When the RTV insulator coating is applied to the insulator surface, it cures to form a gel-like film. Under clean conditions, this film exhibits excellent hydrophobicity. When the film surface is covered with contaminants, the small hydrophobic molecules within the film can quickly migrate through the contamination layer to its surface, imparting superior hydrophobicity to the contaminated layer. This makes it difficult for the surface of the contaminated layer to become wet under humid conditions like fog, dew, or drizzle. Even if the contaminated layer becomes wet over time, it does not form continuous water flow or water films but rather remains as numerous isolated droplets, thereby significantly reducing the leakage current and greatly increasing the pollution flashover voltage of the insulator.
Significantly increases the pollution flashover voltage of external insulation on power transmission and transformation equipment, potentially boosting it by over 200%, ensuring the safe operation of power equipment.
The RTV insulator coating features excellent electrical and mechanical properties, strong hydrophobicity and hydrophobic migration, strong adhesion, and long service life.
As a single-component coating, it requires no mixing; once the sealed package is opened, it can be directly sprayed or applied to the insulator surface. It cures upon contact with moisture in the air, ensuring quality, minimizing waste, and allowing simple application.
The RTV Silicone Rubber Coating's residue is non-conductive after combustion, leaving no safety hazards for equipment operation.
The coating's flammability rating meets at least FV-1, making it especially suitable for insulation and anti-pollution work on DC transmission and transformation equipment in power systems.
Under normal operating conditions, power insulation equipment coated with RTV Silicone Rubber Coating for insulators is maintenance-free, saving substantial labor and resources for external insulation cleaning.
RTV antifouling coatings are versatile and have multiple applications in various industries, mainly in marine environments. They are applied to underwater surfaces, protecting structures from fouling agents and reducing maintenance costs.
Marine vessels such as commercial ships, fishing boats, yachts, and other watercraft use RTV antifouling coatings to improve fuel efficiency, reduce drag and damage caused by barnacle and algae colonization, and prolong the vessel's life.
In the offshore industry, these coatings are used to protect underwater components such as pipelines, platforms, and other marine structures from the elements and to reduce maintenance and replacement costs.
Moreover, RTV antifouling coatings are also used in the swimming pool industry, providing a long-lasting protective barrier against chemicals and UV radiation, reducing the frequency of maintenance and upkeep.
In conclusion, RTV antifouling coatings have extensive applications in various industries such as the marine industry, offshore industry, and swimming pool industry, providing long-lasting protection to underwater components and reducing maintenance costs.
