Successfully developed W-1 paper sizing agent

The surface sizing of paper is an important means to improve the surface quality of paper or paperboard. The surface sizing agents used in China at present are starch, modified starch, PVA, etc. The amount of other surface sizing agents is still relatively small, compared with foreign countries. In comparison, there is a big gap between the variety of products and the performance of products. For this purpose, Shanghai Hadafu Auxiliary Co., Ltd. developed a W-1 paper sizing agent based on domestic and foreign products. It is a new polymer surface sizing agent that can be widely used for coating base papers. , printing writing paper, offset paper, kraft paperboard, etc., can effectively improve the paper's water resistance, surface strength, folding resistance, tensile strength, LCT brushing strength, stiffness and smoothness, reduce air permeability, improve printing performance, etc. . The product has good compatibility with starch and modified starch.
