White carbon black, also known as silicon dioxide, is an inorganic compound. Due to its uniform particle structure and large surface area, it is widely used in many fields. When white carbon black is used as a pigment filler, it has the following advantages:

Improve hiding power: As a white, amorphous fine powder, white carbon black has a high degree of dispersibility and a large specific surface area, which enables it to effectively increase the hiding power of the coating, making the coating more uniform and thick.
Improve leveling and gloss: Adding white carbon black to the coating can significantly improve the leveling of the coating, making the coating smoother and flatter. At the same time, it can also adjust the gloss of the coating to a certain extent, making the coating present a more ideal visual effect.
Enhance pigment performance: White carbon black has the characteristics of high temperature resistance and good chemical stability. These characteristics enable it to enhance the weather resistance, heat resistance and chemical stability of the pigment when used as a pigment filler, thereby extending the service life of the coating.
Improve product quality: As a pigment filler, white carbon black can make the coating more stable during the production process, reduce fluctuations and errors, and thus improve the quality of the product.
Increase transparency and saturation: Especially in organic pigments, adding fumed silica can greatly improve the anti-aging performance, brightness, hue and saturation of the pigment, making the modified organic pigment more high-end and with a wider range of applications.
In addition, silica is also widely used in cosmetics, food packaging and other fields due to its non-toxic, odorless and easy-to-color properties. In cosmetics, it can produce a "ball bearing effect" and a "soft focus effect", making the skin smoother and softer, and preventing pigment sedimentation; in food packaging, it can preserve fruits and vegetables, and is used as an efficient fungicide to prevent and treat fruit diseases.


In summary, silica has many advantages as a pigment filler, which can significantly improve the quality and performance of coatings and broaden their application range.
