Bentonite claycan disperse 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.YH-938 needs polar activator to be fully disperse .The available polar activators are as follows:propylenecarbonate,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 is10-20% of organic bentonite.
