Specifications

 Organic bentonite: HY-738B

Product features
   HY-738B (new organic bentonite) is a kind of modified rheological additive with high efficiency of gelling 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 of paint, ink, sealant, oil drilling, grease etc.

Appearance and physicochemical indexes

Use method
   HY-738B can disperse at normal atmospheric 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 fully disperse. The available polar activators are as follows: propylene carbonate, methanol/water (95/5), ethanol/water (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 (brown paper bag) and internal package (polyethylene film bag). The valve bag is also available and the weight is usually 25 ± 0.25Kg. The package can also be customized. If stored in dry place and kept packaged (at the temperature of 0℃~30℃), the organic bentonite is effective within 36 months.
