Surface Sizing Agent for Paper Chemicals

Surface Sizing Agent for Paper Chemicals Product Introduction: 1.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. 2.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. 3.This product is suitable for corrugated paper, box board paper, white bullock cards, coated paper, etc. Major Technical Indicators: Item Surface Sizing Agent Appearance Milky white to reddish milky liquid Viscosity ≤200 mPa.s(25ºC) Ionic Cationic Solid content 28±2% PH value 3-5 Performance Characteristics 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. Advantage: Improve the surface strength of the paper,reduce the paper's drop hair and powder in the process of printing. Improve the printing performance of paper,increase the color of ink after printing. Improve water resistance of paper and reduce internal sizing agent. Excellent mechanical stability,low foam emulsion. Usage: Use level 2-5KG/T. When the surface starch is cooled below 50ºC,add emulsion about 5-10% relative to starch. It can be used with fluorescent brighteners and fuel. Attention: Avoid mixing with anionic auxiliaries. Store in a cool place,avoid sun exposure. Six months at room temperature. Package: Packing in 200KG or 1000KG polyethylene drums.
