Surface Sizing Agent, Purity : 30%+/2, CAS No. : 24981-13-3

Our surface sizing agent is widely used in paper industry, it could improve the property of paper or paperboard, including the surface intensity,water resistance, stiffness, ring crush strength,smoothness, printing and so on.
Our Surface Sizing Agent has the good properties as follows:
1. Cationic surface sizing agent is styrene ester copolymer of a new generation of products 
2. It can effectively combine with starch, giving starch coating good crosslinking intensity and hydrophobic properties 
3. Product is small amount to add, low cost and convenient to use 
4. It also has good film forming, can significantly improve the water resistance and ring crush compression resistance of cardboard paper and corrugated paper 
5.Effectively improve the water resistance and ring crush compression resistance of cardboard paper and corrugated paper, no aging period and uneasy to  get damp 
6.It can completely replace internal sizing agent 
7.It can be used with the original starch, reducing the production cost 
8. Excellent mechanical stability, less bubbles in operating process
