Cationic Surface Sizing Agent for Paper Making

This product is a kind of styrene-acrylic ester high molecular polymer,it can be used with starch to do surface sizing on paper, increase the surface strength of paper,thereby to achieve the best water resisting property.

The product is weak cationic, it can be used with cation and nonionic additive, such as cationic starch,basic dye and polyvinyl alcohol etc, but cannot be mix used with additive of strong cation.

The consumption of the product depends on the quality of base paper, internal sizing and size resistance. It is usually 0.5-2.5% of oven dry weight.
