Audited Supplier | Nano calcium carbonate for paint has the characteristics of ultra-fine and ultra-pure. The crystal shape and particle size are effectively controlled during the production process. The surface of the product is surface-modified by resin acid and special dispersant, and has good compatibility with paint resin. Therefore, it has the advantages of small particle size, narrow particle size distribution, good transparency, high gloss and moderate fluidity in paint products, and has a spatial three-dimensional structure and good dispersion characteristics. |
| The nano-calcium carbonate special for paint produced by our company can play a skeleton role in paint coating, and has the advantages of fine, uniform, high whiteness, good optical performance and so on. It has space negative effect. In the paint making, it can make the dense density of Lidefen County in the formula float and play a role in preventing settlement. After the paint is made, the whiteness of the paint film increases and the glossiness is high, but the covering ability does not decrease. |
