6000 mesh water-ground calcium carbonate
1. Application fields:
Applied to coatings, various plastics, rubber and other industries.
2. Features:
Small particle size, uniform distribution, no agglomeration, no sedimentation, good stability, easy to disperse. The quantum size effect, small size effect, surface effect and macro quantum effect of nano calcium carbonate due to its small particles enable it to be organically combined with architectural coatings, thereby improving the coating's performance in terms of adhesion, hiding power, anti-powdering, etc., improving the gloss of the paint film, and making it smooth and delicate. At the same time, it can greatly reduce costs.

IV. Usage:
Users can pre-disperse part of TiO2 and physical fillers into slurry for standby use, and mix them according to the proportion when mixing the paint.
The amount of addition can be added according to the formula system, and it is recommended to add 15-20 parts.
