Organic bentonite: YH-938

Product features

YH-938 (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. YH-938 is equivalent to the following overseas products: Bentone 34, TIXOGEL MP, TIXOGEL VP etc.

Use method

YH-938 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. YH-938 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 10~20% of organic bentonite.

The amount of YH-938 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.
