Product features
HY-S2 is a new kind of organic bentonite with the properties of easy dispersion and self-activation,It is an upgradeproduct based on HY-2. It can be used in medium to high polar solvent systems (such as ester, ketone, alcohol, etheretc.). 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
Use method
HY-S2 is unnecessary to be used as pre-gel. It can be directly added during any period of the preparation processof coating and ink. Compared with ordinary products, it has better efficiency and the dosage is less.
The amount of HY-S2 is usually 0.2*2.0% of the system (by weight).
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.
Package and storage
The package consists of external package (brown paper bag) and internal package (polyethylene film bag). Thevalve bag is also available and the weight is usually 25 ± 0.25Kg. The package can also be customized. If stored in dryplace and kept packaged (at the temperature of 0℃ ~30℃ ), the organic bentonite is effective within 36 months.
