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).
