Moisture Resistant SAE Surface Sizing Agent JH-600 for Packaging Paper
JH-600 is a cationic styrene-acrylic (SAE) surface sizing agent developed for packaging paper that demands reliable moisture resistance. Its customized anti-moisture reversion molecular structure forms a dense hydrophobic film on the paper surface, preventing strength loss and box collapse during high-humidity storage, cold chain logistics, and long sea freight. With a 30% solid content, low viscosity, and excellent starch compatibility, it can be applied directly in existing surface sizing processes without major modifications.
Unlike conventional sizing agents, JH-600 retains its hydrophobic performance over extended periods in humid environments, avoiding the gradual failure common to other products. It can fully replace internal sizing for production, delivering instant and durable anti-moisture effects after drying, which shortens production cycles and improves overall efficiency.
Key Selling Points
Long-term moisture resistance: Maintains hydrophobic performance in humid conditions, preventing gradual loss of water resistance over time (source: product selling point).
Replaces internal sizing: No curing period required; finished paper gains immediate and durable anti-moisture properties, reducing production time (source: selling point).
Starch compatible: Directly mixes with industrial starch liquid, cutting overall chemical costs without changing existing dosing systems (source: selling point).
Preserves physical strength: Retains ring crush strength and surface rigidity under high humidity, avoiding sharp drops in packaging paper indexes (source: selling point).
