HY-738B Organic Bentonite  

1.Product features:

HY-738B (new organic bentonite) is a kind of modified rhealagical additive with high efficiency of geiling and thixotropy. It can be used in low to medium polar systems. HY-738B is equivalent to the following overseas products: Bentone 34, TIXOGEL MP, TIXOGEL VP etc. And it is widely used in the fields such as paint, ink, sealant, oil drilling, grease etc.

2. Appearance and physicochemical indexes:    

3.Use method:

HY-738B can be dispersed 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.HY-738B needs polar activator to be fully dispersed.The available polar activators are as follows:propylene carbonate, methanollwater (95/5), ethanollwater (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.
