Application of silicone oil in polishing agents
Fluidity: Silicone oil gives the polish good fluidity, making it easy to apply evenly.
Hydrophobic film: Silicone oil can form a hydrophobic film on the surface to enhance gloss and weather resistance.
Application fields: Polishing agents formulated with silicone oil are not only used in automobiles, but are also widely used in the surface treatment of leather products, furniture, plastics, rubber and other materials.
Types and viscosity of silicone oil
Viscosity range: The viscosity of commonly used dimethyl silicone oil is 100~1000mm²/s, and the addition amount is 0.5%~10%.
Performance impact: Dimethyl silicone oils of different viscosities have a significant impact on the performance of polishing agents.
Application of silicone oil in glass and ceramic surface treatment
Hydrophobicity and lubricity: Silicone oil can firmly adhere to glass and ceramic surfaces, providing hydrophobicity and lubricity.
Treatment method: Usually use dimethyl silicone oil with a viscosity of 100~500mm²/s, prepare a 3%~5% solution, and treat the material by dipping or spraying.
High temperature treatment: The treated glass or ceramic is treated at high temperature for 0.5 to 1 hour to enhance the adhesion of silicone oil.
Application of silicone oil in pharmaceutical packaging
Prevent drug adhesion: The inside of the bottle treated with silicone oil can prevent drug adhesion.
Reduced wear: Treated bottle exteriors reduce scratches and wear during transportation.
Application of silicone oil in insulator surface treatment
Electrical insulation: Glass and ceramic insulators heat-treated with silicone oil can significantly improve the electrical insulation.
Prevent leakage: In high-humidity environments, silicone oil treatment can prevent leakage.
Natural cleaning: The surface treated with silicone oil can naturally remove dust and maintain insulation under the action of wind and rain.
- Application of silicone oil in coatings and plastics
Paint and ink applications
Improve coating properties: Adding a small amount of dimethyl silicone oil can prevent uneven color and make the coating surface more uniform and smooth.
Increase the brightness: The addition of silicone oil helps to improve the brightness and gloss of the coating.
Defoaming effect: High viscosity dimethyl silicone oil can be used as a defoaming agent to improve the stability of the coating.
Compatibility issues: Silicone oil may not have good compatibility with other coatings and should not be mixed at will.
Adding amount: The recommended adding amount of silicone oil is between 0.01% and 0.5%.
Application of silicone oil in plastic industry
Mold release: Dimethyl silicone oil acts as an internal release agent to improve the mold release of plastics.
Dispersibility: Silicone oil can improve the dispersion of inorganic fillers in the resin and ensure uniform mixing.
Fluidity: The addition of silicone oil improves the fluidity of the resin and facilitates processing and molding.
Surface properties: Improve the lubricity and wear resistance of the product surface.
Application of silicone oil in specific plastic resins
POMPA, HIPS, ABS: These resins with added dimethicone are widely used in the manufacture of wear-resistant and lubricating plastic parts.
Application of silicone oil in agricultural films
Light stability: In low-pressure polyethylene agricultural films, dimethyl silicone oil is used in conjunction with dispersed hindered amine or hindered phenol light stabilizer systems to reduce the amount of light stabilizer and improve light resistance.
Strength improvement: The addition of silicone oil improves the strength of the film.
Light transmittance: Improves the transmittance of ultraviolet light in the short wavelength range effective for plant growth.
