4、 Precautions
1. Do not mix this product with other antirust products to avoid affecting the use effect.
2. 0 ~ 35 ℃ indoor sealed storage, avoid sunlight, rain, prevent moisture and impurities into, and pay attention to indoor ventilation and exhaust.
3. Do a good job of fire fighting when storing and using to avoid fire.
4. During long-term storage, a small amount of soft impurities will settle, which is a normal phenomenon and does not affect the antirust effect.
5、 Packaging
Packed in barrels or 170 kg.

4、 How to use it
This product is added in the process of wet ultra-fine grinding without dilution. It can be directly added into the pigment to be dispersed and stirred evenly. The amount of this product is generally 0.1-1.0% of the pigment absolute dry weight. When it is added in the process of dry ultra-fine grinding, it can be diluted with water according to the need, and the amount is 0.1-0.2% of the pigment absolute dry weight.
5、 Packaging
1. The dispersant is packed in plastic drum with net weight of 250kg. Other packages can also be used according to the needs of users.
2. The storage temperature is 5 ~ 30 ℃, and the shelf life is 12 months.
3. If the storage temperature of the product is too low, a small amount of crystal will appear at the bottom, which will not affect the dispersion effect after dissolving.
