Specifications

HY-S2 is a new kind of organic bentonite with the properties of easy dispersion and self-activation.

     Organic bentonite: HY-S2
Product features
   HY-S2 is a new kind of organic bentonite with the properties of easy dispersion and self-activation. It can be used in medium to high polar solvent systems (such as ester, ketone, alcohol, ether etc.). It is widely applied in the fields of anti-corrosion paint, marine paint, industrial decorative paint, auto-primer, adhesive and sealing materials etc.

Appearance and physicochemical indexes

Appearance	White power
Loss on ignition	42.5~45.5%
Fineness,76um (200 mesh)	≥95%
Moisture content	0.8~3.5%
Viscosity	≥0.9Pa·s

Use method

   HY-S2 is unnecessary to be used as pre-gel. It can be directly added during any period of the preparation process of coating and ink. Compared with ordinary products, it has better efficiency and the dosage is less.

Suitable solvents
   It can be used in the following solvent mixture system: alcohol, ketone (more than 4 carbon atoms), polythene glycol, glycol ethylene ether, propylene carbonate and aliphaticn, aromatic hydrocarbon, phthalate, plant oil etc. If the above systems are mixed with methanol, ethanol, isopropanol, butanol, methyl ethyl ketone, acetone, ethyl acetate, HY-S2 can present better performance. Generally, the amount of the high polar solvent should not be more than 20% of the solvent system.

Dosage

The amount of HY-S2 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 the temperature of 0°C~30°C), the organic bentonite is effective within 36 months.
