Specifications

HY-34 is a new kind of organic clay with the properties of easy dispersion and high thixotropy.

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
Loss on ignition	37~40%
Fineness,76um (200 mesh)	≥95%
Moisture content	0.8~3.5%
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°C~30°C), the organic bentonite is effective within 36 months.
