Both white carbon black and black carbon black are fine granular fillers that can be used in coatings. Their role in coatings is as follows:

Adjust the rheological properties of coatings: Silica can control its fluidity by increasing the viscosity of coatings, so as to achieve better coating effects.

Improve the hiding power and gloss of the paint: the addition of silica in the paint can increase the hiding power and gloss of the paint, making the surface of the paint smoother and more uniform.

Increase the durability of coatings: Silica can improve the abrasion and chemical resistance of coatings, making them more durable.

Adjust the color of the paint: Silica can adjust the color of the paint to make it more pure white or lighter.

In short, silica and black carbon black play many roles in coatings, which can make the coating stronger, more beautiful and suitable for different application scenarios.
