HY-778 organic bentonite is an upgrade of HY-768 with the properties of self-activation, high effectiveness of geling, high thixotropy, easy to disperse, and high transparency. It can be used in low to high polarity system. HY-778 series products are widely used in areas like coating, painting, ink, sealant and cosmetic. Its comprehensive functions are better than the same series products 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: under the action of moderate polarity activator, the speed of dispersing and geling becomes faster, and the dispersing fineness is very small. (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(<0.044mm)(325mesh) % ≥95 Moisture content % 0.8~5.0 Viscosity,Pa·s ≥0.9 Operation method: HY-768 does not to be used as pre-gel, it can be directly added into any steps of the processing of coating and ink preparation. It has higher effectiveness of application than the normal products, so you need to reduce the amount when use it. Operation amount:The amount of HY-708 added to the system is generally 0.2-3.0% of total weight. Packaging and storage: Brown paper packages plus internal polyethylene film bags, or paper packages with valve mouths are used. The weight of each package is generally 25±0.25 kg according to customer demands. Keep it in dry places with temperature of 0°C-30°C. The quality guarantee period is 36 months.
