Product overview

   It is a copolymer formed by emulsion polymerization based on butadiene, styrene and fewer carboxylic acid and other additives, which is a milky white water dispersion with bluish violet luster. Styrene is high in proportion, powerful in adhesive force and bond strength, favorable in mechanical and chemical stability, good in liquidity and storage, large in loading level, etc. Since there are little residual benzene monomers, the papermaking coating Carboxy styrene-butadiene latex in the industry of the papermaking, carpet, textile, decorations environmental protection (carbon carving and plastic flower), architectural decoration (modified cement mortar, wood glue, modified asphalt and oilfield drilling), etc. is used in the whole series of latex needed in paper and cardboard coating industry, and is suitable for the surface coating, bottom coating and bonding of decorative base paper, medium and high-grade art paper, white board, paperboard, box board paper, etc. Carboxy styrene-butadiene latex not only can improve the production efficiency and reduce the cost, but also can boost the performance and quality of paper and paperboard. Its specific performance is reflected at the following stage: 

     Latex paper manufacturing stage 

    It is easy in coating operation, is liable to mixing with other coatings due to excellent chemical stability, can adopt high-speed mixer due to excellent mechanical stability, can be added at high temperature due to excellent thermal stability, and would not change in use. Beautiful coating: It is free from coating spots, stripe, splashing and gum adding. High production efficiency: It can be used for coating at high speed, without polluting backup roll and calender roller, and is powerful in coating adhesive force. Beautiful and elegant coated paper: It is high in whiteness, favorable in the base paper gloss, printing gloss, flatness, etc. 

     Printing stage 

     Excellent printing adaptability: The coating layer doesn't fall off, with high surface strength. It has a high printing efficiency, which can improve printing speed, without hot bubble. It can conduct immediate superposition. It is excellent in ink absorbency and bondability, and can balance the breathability and anti-foaming property when improving them. It is excellent in ink absorbency and is free from spot. The printed matters are beautiful in the appearance. The carboxylic butadiene-styrene latex belongs to terpolymer, which has higher bond strength and adhesive force, is superb in stability and liquidity, large in loading level, good in model forming, excellent in mechanical, chemical and freeze-thaw stability, and good in compatibility with pigment and filler, etc.
