HY—708 Organic Bentonite Product features: HY-708 is a kind of organic bentonite which its raw materials is natural calcium base bentonite and it is formed by the processing of highly purified, modified, and organic modified. It is suitable for low to medium non-polar solvent paint, ink, etc. 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: HY-708 organic bentonite has the property of anti-sagging in the system. Appearance, physical and chemical indexes Appearance Grey powder Loss on ignition ％ 29.5～32.5 Granularity（＜0.076mm ） ％ ≥95 Moisture content ％ 0.8～3.5 Viscosity，Pa?s ≥0.9 Operation method HY—708 can be dispersed at normal temperature, we suggest to make pre gel first, add before grinding, and high speed shearing equipments are necessary to have the best dispersing effectiveness. HY—708 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(95/5).The amount added of polarity activators can be adjusted according to the different systems. Generally speak, the appliable amount is 30-50% of the organic bentonite. 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℃-30℃. The quality guarantee period is 36 months.Uses: paint , ink thickening agent ,antisettling agent Synonyms: Quaternary ammonium compounds, (hydrogenated tallow alkyl)trimethyl, salts with bentonite;Trimethyl(hydrogenated tallow)ammonium bentonite
