Silicone-modified anionic aliphatic waterborne polyurethane dispersion, free from formaldehyde and NP; balances high modulus with adequate elongation, delivering smooth, crystal-clear, high-gloss films with outstanding UV and yellowing resistance; designed for leather finishing and PVC/PET flexographic printing ink systems.
PUD · Coating & Ink
YT-6131 is a silicone-modified anionic aliphatic waterborne polyurethane dispersion independently developed by our company. The product is green and eco-friendly, containing no hazardous substances. It provides balanced mechanical properties combining high modulus with good elongation; the coating film is smooth, transparent and full-bodied with high gloss, and exhibits excellent UV and yellowing resistance. Suitable for various leather finishing processes, it delivers outstanding adhesion to PVC and PET flexible film substrates, making it an ideal film-forming agent for waterborne inks and plastic coating systems.
Store in a cool, dry, well-ventilated place at 5–30 °C; shelf life 6 months. Avoid freezing and light. Transport as non-hazardous goods.
