method of application
YH-908A, it is bettor 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,o it is best to use high-shearing device. YH-908A 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.
The amount of YH-908A is usually 0.2~3.0% of the system (by weight）.
