Application of White Carbon Black in Coatings

Extinguishing agent: The refractive index of amorphous white carbon black is 1.457, which is similar to the refractive index of conventional resin coatings, making it the preferred extinction agent for high-end coatings. After adding white carbon black, the coating can produce matte and matte effects, meeting the market's demand for coatings with different glossiness. In varnish, white carbon black not only provides good optical properties, but also improves the scratch resistance and wear resistance of the coating.

Thickener and thixotropic agent: White carbon black has strong adsorption capacity and dispersibility due to its unique nanostructure and huge specific surface area.

In coatings, it can be used as a thickener and thixotropic agent to improve the viscosity and suspension stability of the coating, preventing the settling of pigments and fillers. This is crucial for improving the construction performance and storage stability of coatings.

Reinforcing agent and filler: Gas phase white carbon black, due to its small particle size and large specific surface area, can be used as a reinforcing agent and filler for coatings to improve their hardness and wear resistance. Adding an appropriate amount of white carbon black to the coating can not only increase the thickness and density of the coating, but also improve the anti permeability and weather resistance of the coating.


Special performance improvement: In the adhesive used for wind turbine blades, strong hydrophobic modified nano scale gas-phase white carbon black has strong stability and can avoid solvent based effects, ensuring the long-term stability and excellent bonding performance of the adhesive. In addition, white carbon black can also be used to prepare coatings with special functions, such as fireproof coatings, anti-corrosion coatings, etc. Through its unique physical and chemical properties, it can improve the fire resistance and corrosion resistance of coatings.
