Product Detail

Product Tags

Physical and chemical properties:

Main component Anionic charged styrene acrylate copolymer
Appearance: Brown aqueous dispersion
Solid content (%) 25±1%
PH value (25 ℃) 4.0-6.0
Viscosity (25 ℃) <30cp

Performance characteristics:

1. Improve the water resistance and surface strength of paper and paperboard, reduce the paper wool and powder
2. Improving printability of finished paper
3. Reducing the amount of sizing agent in pulp

Usage and precautions:

1. WS is weakly negative and can be used in surface sizing with anionic, nonionic or weakly cationic starches;
2. Through the metering pump, it is continuously added into the sizing tank or the sizing pipe
3, less foam, sizing process can be added or less defoamer.
4. It is not suitable to keep it below 0 ℃ for a long time, nor to explode it for a long time;
5. The addition of anionic additives will affect the sizing effect.
6. The dosage of sizing agent depends on the sizing requirements, and the recommended dosage is not more than 2kg / t-5.0kg/t paper

Packaging and storage:

According to the customer’s requirements, we can provide different packages of 50, 200 or 1000 kg. Store in a cool, dry and ventilated place, especially to prevent frost.
