Cationic surface sizing agent TK-SA80 is a copolymer synthesized by styrene and acrylic ester. It has an effective combination with starch, giving the starch coating good cross-linking strength and hydrophobic property. TK-SA80 has features such as a small amount of addition, low costs, easiness of using, etc.. With a good-forming property, it can significantly improve the water resistance and ring crush compression resistance of cardboard paper and corrugated paper. Technical Indicators: Appearance: Milky white to light brown liquid Ionic: Cationic Solid content: 27% Performance Features 1. Can effectively improve the water resistance and ring crush compression resistance of cardboard paper and corrugated paper, no aging period and uneasy to get damp 2. Can completely replace the using of internal sizing agent 3. Can be used with the original starch thus reduce the production cost 4. with excellent mechanical stability, few bubbles in operating process 5. sizing degree can be quickly adjusted because of low viscosity and easiness to be measured. Application 1. Dosage: 1.5-3.5 kg per ton of paper. Aluminum sulfate 2-3 kg per ton of paper. PH value of the starch liquid should be controlled under 5. 2. When using, cooled the starch liquid which is already pasting to below 75. And then add the product slowly to material mixing tank when stirring. After stir well, computer sizing, or use the metering pump and join the product continuously before putting starch in sizing machine. Intention It inadvisable to store a long time after opening the drum, and prohibit to mix with alkali directly. Rinse when touch people. Storage: Store in a dry room, less than 30. Pay attention to prevent frozen and sunscreen. Packing 200kg1000kg plastic drums. 200kg1000kg plastic drums.
