Product name: Nano Precipitated Barium Sulfate AY-JB53C
AY-JB53C 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 powder coating, water-base or oil base coating and exterior coating, etc. Furthermore, it can significantly improve the products gloss, hardness, impact resistance and adhesion while reducing costs.
