Waterborne Polycarbonate PUD for Leather and Textile Surface Coating
Waterborne Polycarbonate PUD for Leather and Textile Surface Coating is a high-performance polyurethane dispersion designed to provide exceptional durability for eco-friendly coating systems. This Polycarbonate PUD forms a tough, flexible film through coalescence upon water evaporation, offering an environmentally compliant solution with low VOC content. The key properties of this Polycarbonate PUD, including superior hydrolysis resistance, excellent abrasion endurance, and soft handle, are achieved by incorporating robust polycarbonate segments into the polymer backbone. It is ideal for creating high-quality, long-lasting finishes on leather and textiles.

Runshine New Materials (Foshan) Co., Ltd. manufactures Waterborne Polycarbonate PUD for Leather and Textile Surface Coating, a high-performance polyurethane dispersion engineered for next-generation, eco-friendly coating systems. This advanced Polycarbonate PUD leverages a molecular design incorporating hydrolytically and UV-stable polycarbonate segments to deliver an exceptional balance of abrasion resistance, chemical resistance, and mechanical durability—all within a low-VOC, solvent-free aqueous platform. The film formation of this Polycarbonate PUD occurs through efficient particle coalescence upon water evaporation, forming a tough, continuous, and flexible film. This process grants the final coating key application benefits such as rapid drying, excellent substrate adhesion, and a soft hand feel, alongside long-term resistance to hydrolysis, scuffing, and discoloration. The superior performance profile is achieved through precise molecular architecture that capitalizes on the inherent robustness of polycarbonate chemistry, making this Polycarbonate PUD an ideal base for formulating high-end, durable coatings for automotive leather, luxury footwear, and performance textiles that meet stringent environmental and performance standards.

Key Features
✧ Exceptional Hydrolytic Stability – The inherent resistance of the polycarbonate backbone to cleavage by moisture ensures long-term integrity of the coating, preventing degradation and tackiness in high-humidity environments or upon exposure to sweat and cleaning agents.
✧ Superior Abrasion & Scuff Resistance – The tough, cross-linked film network provides outstanding resistance to mechanical wear, scuffing, and repeated rubbing, significantly extending the service life of high-traffic leather goods and performance textiles.
✧ Eco-Compliant Waterborne Platform – Formulated as a solvent-free aqueous dispersion, it features negligible VOC content, is non-flammable, and aligns with the strictest global environmental and workplace safety regulations (e.g., REACH, OEKO-TEX®).
✧ Excellent Flexibility & Toughness – A meticulously balanced hard-to-soft segment ratio grants the coating an optimal combination of high tensile strength and elasticity, allowing it to withstand repeated flexing, folding, and stretching without cracking or delaminating.
✧ Strong Substrate Adhesion – This Polycarbonate PUD exhibits excellent adhesion to a wide range of challenging substrates, including full-grain leather, synthetic PU/PVC leather, and various woven and non-woven textiles, ensuring reliable performance.
✧ Desirable Soft Hand Feel – Imparts a supple, natural, and pleasing tactile sensation to the coated surface, a critical quality parameter for premium leather finishing and high-end apparel coatings.
✧ High Resistance to Chemicals & Stains – The dense, chemically inert film structure offers excellent protection against oils, greases, and common household chemicals, facilitating easy cleaning and maintenance.
✧ Enhanced Thermal & Yellowing Resistance – The saturated polycarbonate chemistry provides superior resistance to thermal degradation and UV-induced yellowing compared to aromatic PUDs, ensuring color and appearance retention over time.
✧ Good Freeze-Thaw Stability – Advanced stabilization technology ensures the dispersion maintains its integrity and performance through multiple freeze-thaw cycles, guaranteeing reliability during storage and shipping in temperate climates.
✧ Broad Formulation Latitude – Demonstrates good compatibility with a wide array of additives, including crosslinkers, wetting agents, thickeners, and matting agents, offering formulators extensive flexibility to tailor final properties.
