HY-758 Organic Bentonite

Product features: HY-758 organic bentonite is a kind of newly modified rheological additive which is based on HY-738B, it has high effectiveness of geling and thixotropy, and it is easy to disperse and its dispersing fineness is very small. It can be used with many products with low to medium polarity solvent system. HY-758B has the same function with the abroad product SD-1. It is widely applied in the areas such as paint, ink, sealant, oil drilling and lubricating grease. And 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) Anti-sediment: our products have the property of anti-sagging in the system. Appearance, physical and chemical indexes: Appearance Grey powder Loss on ignition % 33.5~36.5 Granularity(<0.076mm) % ≥95 Moisture content % 0.8~3.5 Viscosity,Pa·s ≥0.9 Operation method: HY-758 can be dispersed at normal temperature, it can increase the visicosity of the system and has a property of thixotropy, and high speed shearing equipments are necessary to have the best dispersing effectiveness. HY-758 needs polarity activator to make it fully dispersed, the applicable polarity activators are as follows:carbinol/water (95/5) , ethanol/water(95/5) and acetone.The amount added of polarity activators can be adjusted according to the systems. Generally speak, the appliable amount is 30-50% of the total weight of organic bentonite. The add method of the products are pre-gel method and powder method which can be confirmed by the customers’ test. Operation amount:The amount of HY-758 added into the system is generally 0.2-3.0% of total weight. Packiaging 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..
