Product name: Super Fine Modified Barium Sulfate AY-6300A
AY—6300A is a new achievement of Onmillion Group after the research and development of a number of research institutions. Adopting the high-tech nanotechnology, the product is organic dense enveloping particles. Its particle size is very small with narrow distribution, high chemical stability, high activation, high dispersion, high whiteness and other characteristics. It can be widely applied to various products, such as water based coatings, plastics, paints, ink and rubber, etc. Furthermore, it can maintain the transparency of the products, and significantly improve the products gloss, hardness, impact resistance and adhesion whilereducing costs.
