Introducing JH-WH3364, a composite surface sizing agent that integrates the reactive waterproof advantage of AKD with the high film-forming toughness of styrene-acrylic resin. Designed for modern papermaking, this dual-functional additive provides immediate sizing effect after drying, eliminating the need for prolonged curing, and significantly improves paper surface strength and printing adaptability.
Key Selling Points
Enhanced Water Resistance & Surface Strength
Combines AKD's chemical reaction with cellulose fiber for long-term hydrophobicity and SAE's tough film for surface reinforcement, achieving dual upgrading in one product.
Immediate Sizing Effect
Overcomes slow curing of pure AKD, as SAE fixes the sizing instantly after drying, allowing direct rolling and delivery for faster turnover.
Improved Printing Adaptability
Reduces paper linting, picking, and ink feathering during high-speed offset printing, making it ideal for cultural and packaging paper.
Excellent Blend with Starch
Perfectly mixes with oxidized and modified starch, ensuring uniform crosslinking and consistent sizing across the paper web.
Operational Stability
Boasts high mechanical shear resistance and low foaming, preventing defects like foam pinholes and stripes during continuous high-speed operation.
Cost Efficiency
Replaces separate dosing of AKD and SAE, simplifying the process and reducing procurement costs while delivering higher efficiency.
