Import Cationic Surface Sizing Agent Tk-Sa80 — Buy in Bulk from Supplier in China

Cationic surface sizing agent TK-SA80 is a styrene-acrylic copolymer designed for paper and corrugated board production, supplied as a milky white to light brown liquid with 27% solid content. Its cationic charge allows strong bonding with starch, enhancing cross-linking and hydrophobic properties to improve water resistance and ring crush compression strength in cardboard and corrugated paper. The agent eliminates the need for internal sizing and reduces production costs by integrating with existing starch systems without aging periods or moisture absorption issues.

The product demonstrates excellent mechanical stability with minimal foaming during operation, and its low viscosity enables rapid adjustment of sizing degrees for precise control. Typical industry applications include corrugated packaging, folding cartons and solid board, where its performance in enhancing structural integrity and moisture resistance is critical. Standard practice in the paper industry involves dosages of 1.5-3.5 kg per ton of paper, with aluminum sulfate at 2-3 kg per ton, and pH control below 5 for optimal starch compatibility.

Buyers in the packaging and paper manufacturing sectors use TK-SA80 to replace traditional internal sizing agents while maintaining or improving quality at lower costs. The product is supplied in 200 kg or 1000 kg plastic drums, with storage requirements limited to dry, temperature-controlled environments below 30°C to prevent freezing or degradation. For bulk orders, confirm packaging options and handling procedures to ensure compatibility with existing production lines.
