KDD 724 is a modified acrylic resin with NC/CAB replacement capability from KDD Chemicals' high-TG quick-drying thermoplastic acrylic resin series, designed for efficient coating and resin modification scenarios. With a high TG value of 130℃, this resin uses butyl acetate/toluene/isobutanol as mixed solvent and has a solid content of 55%, combining high hardness and excellent leveling.
High-TG and high-hardness features - TG value up to 130℃, excellent film hardness, tough and scratch-resistant surface, suitable for high-demand protection scenarios.
Broad-spectrum system compatibility - Excellent compatibility with UV, thermoplastic, hydroxyl acrylic resins, etc., with high formulation flexibility.
Efficient quick-drying advantage - Fast drying shortens production cycle, suitable for air-drying/low-temperature coating processes, improving production efficiency.
Replacement and upgrading value - Can directly replace NC or CAB cellulose, optimizing cost structure while maintaining performance.
Electroplated part topcoat: Surface coating of air-drying/low-temperature electroplated parts, improving hardness and weather resistance, ensuring long-lasting bright appearance.
General single-component paint: Preparation of single-component metal paint and plastic paint, simplifying construction process and adapting to mass production needs.
Resin modification and upgrading: Used as a modifier to improve the hardness and drying property of other resins, expanding the application range of original systems.
PU system optimization: Added to PU hydroxyl systems to significantly improve drying performance, enhancing construction efficiency and coating stability.
