Products HY-738B Organic Bentonite Product features: HY-738B (new organic bentonite) is a kind of modified rhealagical additive with high efficiency of geiling and thixotropy. It can be used in low to medium polar systems. HY-738B is equivalent to the following overseas products: Bentone 34, TIXOGEL MP, TIXOGEL VP etc. And it is widely used in the fields such as paint, ink, sealant, oil drilling, grease etc. Appearance and physicochemical indexes: Appearance White power Loss on ignition 30 ~ 33% Fihneness,76un(200mesh) ≥95% Moisture content 0.8 ~ 3.5% Viscosity ≥20Pa?s Use method: HY-738B can be dispersed at normal temperature.It is better to be used as pre-gel.It should be added before grinding your products (such as paints, pigments, coatings etc.). To get the best dispersion effect, it is best to use high-shearing device.HY-738B needs polar activator to be fully dispersed.The available polar activators are as follows:propylene carbonate, methanollwater (95/5), ethanollwater (95/5)or acetone. The proper amount of polar activator can be adjusted according to different systems. Generally，the amount of polar activator is 30-50% of organic bentonite. Application: □ordinary paint and mill base □ink □adhesive □industrial paint □anti-corrosion paint □marine paint □grease □oil drilling Dosage: The amount of HY-738B is usually 0.2-3.0% of the system(by weight. Package and storage: The package consists of external package(kraft paper bag)and internal package(polyethylene film bag).The value bag is also available and the weight is usually 25±0.25Kg.The package is according fo the customer's reguest .If stored in dry place and kept packaged (at the temperature of 0°C-30 °C),the organic bentonite is effective within 36 months.
