Nano (water-based) calcium carbonate is used in industries such as water-based coatings, water-based inks, various plastics, rubber, papermaking, PVC pipes, non-woven fabrics, leather, etc.
lScope of application:
Used for water-based coatings, water-based inks, various plastics, rubber, papermakingIndustries such as PVC pipes, non-woven fabrics, leather, etc.
lProduct Features
Small particle size, uniform distribution, good stability, and easy diffusion.
Due to the characteristics of nano calcium carbonate products, such as small particles, quantum size effect, and small size effect,
Surface effects and macroscopic quantum effects enable it to interact with architectural coatings, thereby improving the adhesion of coatings,
Covering ability, resistance to binding and crushing performance, improving the gloss of the paint film to make it smooth and delicate to the touch, while significantly reducing production costs.
