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 be fully dispersed. 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.

The amount of HY-738B is usually 0.2*3.0% of the system (by weight).

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 O°C ~ 30°C ), the organic bentonite is effective within 36 months.
