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.
