Styrene-maleic anhydride copolymer sizing agent

Ⅰ. Characteristics

Tiancheng is one of the world`s largest manufacturers of Alkyl Ketene Dimer ( AKD Wax ) with 20 years experiences and the largest and best manufacturer of Cationic Reagent (3-Chloro-2-hydroxypropyltrimethyl Ammonium Chloride/quat 188/CHPTAC), raw material for producing cationic starch in China. Other featured products:General AKD Emulsifier 25%, Quat 188 69%,Polymer emulsifier 40%, PolyDADMAC 40%,Wet strenght agent 12.5%/25%, Styrene Acrylic Copolymer, Fixing Agent 50%, Poly Aluminium Chloride, Sodium Gluconate Oxidized Starch,ect. SAE-TC174 It has those features such like less dosage, easy to be used. It can improve the surface strength, water-resisting property and printability of papers. Beside it can reduce paper slip, picking and tinting in the process of printing. With more dosage it can improve the surface strength effectively, thus the cost will be reduced. .
