HY-778 organic bentonite is a kind of newly modified rheological additive with activation, high effectiveness of geling, high thixotropy, easy to disperse, small dispersion fineness and high transparency. It can be applied in low to high polarity systems. HY-768 organic bentonite is widely used in the ares such as coating, paint, ink, sealant and cosmetic. Its comprehensive capabilities are better than the same product abroad. It has the functions as below: (1) High viscosity: the product has high gel viscosity and strong thixotropy in low to medium polarity solvent system or resin system. (2) Easy to disperse: it doesn’t need to use polarity activator when it is dispersed, the speed of dispersing and geling is very fast, and the dispersing fineness is very small, which is better than the same product in domestic market. (3) High transparency: due to its high transparency, the dispersing fineness is very small, thus the transparency is very high. Appearance, physical and chemical indexes: Appearance: Grey powder Loss on ignition: 36.5~39.5 Granularity(<0.076mm): ≥95% Moisture content: 0.8~3.5% Viscosity,Pa•s: ≥0.9
