Surface Sizing Agent

          is a synthetic copolymer of high molecular emulsifier 

and styrene ester monomer. It mixes well with starch and 

provides the starch coating with excellent cross-linking strength

 and hydrophobic property. It’s featured by low consumption, 

free odor, low foaming, long foam inhibition period and excellent 

film forming, and it can significantly improve the water resistance 

capability and ring pressure strength of corrugated paper and 

cardboard paper. It is a sufficient substitute for internal sizing 

agent and has no maturation period. It is applicable to various 

types of surface sizing machines.
