JH-300 surface sizing agent is a new generation product of the company developing, it has many characteristics, such as small adding amount and tons of paper only need 2-3 kg, easy to operate, etc. The product has good film, and it can significantly improve liner board, the water resistance of corrugated board and compressive strength, improve the surface strength of paper and printability, significantly reduce printing process of shedding hair, powder and paste version phenomenon. The improving of surface can add more appropriate amount of materials and reduce the cost.

三、Performance characteristic
1. It can significantly improve liner board, the water resistance of corrugated board and compressive strength.
2. It can improve the surface strength of paper to replace or reduce the amount of internal sizing agent.3. It can increase the printing adaptability of paper to make print graphic clarity, colorful, strong stereoscopic.
4. It has excellent mechanical stability and produces small air bubbles in the course of operation.
5. The cost-effective of the product is better than import.
四、Use ways:
1. Usage : 2-3 kg / ton of paper.
2. While using, at the beginning of starch gelatinization (above 70°C) become translucent, it will dope in the state slowly stirred by adding starch paste pot, and then continue starch gelatinization process to meet the technological requirements.
五、Packaging, storage
It is packaged by 200 kg, 1000kg plastic barrels. And stored in a cool (4-30 ° C) in order to avoid frozen and heat.
Storage period: 3 months
