Organic bentonite: HY-34
Product features
HY-34 is a new kind of organic clay with the properties of easy dispersion and high thixotropy. It can be used in low to medium and some high polar systems. With only a small amount of activator and fast shearing, it can disperse. And it has advantageous properties of anti-sediment and anti-sagging.
Appearance and physicochemical indexes
Appearance | White power |

Viscosity | ≥0.9Pa·s |
Use method
HY-34 can disperse and dissolve in the organic solvent and resin system at normal atmospheric temperature. And the viscosity of the system can be rapidly increased and the system has the property of thixotropy. To increase its properties of dispersion and thickening, it needs fast shearing and polar additive while dispersing. 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 20~40% of organic bentonite. It can be directly added or used as pre-gel. You can decide which addition method is better through test.
Application
ordinary paint and mill base ink
auto-primer industrial paint
anti-corrosion paint cosmetic
carpentry finish carpentry primer
Dosage
The amount of HY-34 is usually 0.2~2.0% 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 0℃~30℃), the organic bentonite is effective within 36 months.
