HY-758 organic bentonite is a kind of newly modified rheological additive which is based on HY-738B, it has high effectiveness of geling and thixotropy, and it is easy to disperse and its dispersing fineness is very small. It can be used with many products with low to medium polarity solvent system. HY-738B has the same function with the abroad product SD-1. It is widely applied in the areas such as paint, ink, sealant, oil drilling and lubricating grease. And it has the functions as below:
(1) High viscosity: the product has high gel viscosity and strong thixotropy in low to medium polarity solvent system or resin system.
(2) Easy to disperse: under the action of moderate polarity activator, the speed of dispersing and geling becomes faster, and the dispersing fineness is very small.
(3) Anti-sediment: our products have the property of anti-sagging in the system.
