This product is a cationic, styrene, acrylate copolymer emulsion surface sizing agent. It is a product for paper making to enhance the surface strength, water resistance, ring crush strength, smoothness and printing performance of paper or paperboard. This product has excellent properties due to its excellent affinity with fiber, good hydrophobicity of the surface sizing film and strong ring pressure enhancement capability. This product can effectively cross-link with sizing starch, and has good film-forming ability. It can improve the printing surface strength and sizing degree of paper. At the same time, it can reduce production costs and improve production efficiency. This product can replace in-pulp sizing. This product is suitable for corrugated paper, box board paper,white bullock cards, coated paper, etc.
Paper Chemicals /cationic Surface Sizing Agent For Paper Industry
Product Description
PRODUCT FEATURES
1. Styrene acrylic surface sizing agent can be aged right off the machine. It can significantly improve thewater resistance and ring crush strength, surface strength, cobb value and other inddexes of cardboard paper, corrugated paper and culture paper.
2. Improve the printing adaptability of paper, making pictures, texts of printed matter legible with bright color and strong stereoscopic sense.
3. It can entirely replace internal sizing agent, shorten the aging period and not easy to getting dampped. So as to control sizeing degree. It can be used with aluminium surface to further improve sizing effect.
4. Using together with the original starch, oxidized starch, cationic starch and PVA to reduce costs.
SIZING MECHANISM
SAE polymer molecules with positive charges form a reticulate water-resistance film by cross-linking reaction with startch. At the same time, SAE cationic macromlecule also binds with fiber anion and mainly adheres to the surface of paper, thus forming SAE water-resistance macromolecule starch chain cross linking and fiber chain crosslinking network structure and becomnig a compact film.

PERFORMANCE & FEATURE
1. In the sizing process, the product has good affinity and retention with fibers, good compatibility and synergistic effect with starch and other additives and dyes. 2. Improving the water resistance and ring compression strength of box board and corrugated paper significantly. 3. Improve the surface strength and water resistance of the paper, completely replace the sizing agent in the pulp, and the paper after sizing completely changes the phenomenon of moisture regain and degumming. 4. It has excellent mechanical stability, less bubbles are produced during operation, and no additional defoamer is needed. 5. It can be used with raw starch, oxidized starch and cationic starch for surface sizing. It has the advantages of low dosage, low cost and remarkable sizing effect. 6. This product is non-toxic, non-flammable, non-explosive, noncorrosive and non-dangerous.
