SiwoPUD®-2560

When coating performance is non-negotiable and flexibility is key, SiwoPUD-2560 rises to the occasion. This aqueous, aliphatic polyurethane dispersion—built on a foundation of polyether and polycarbonate chemistry—delivers the best of both worlds: remarkable mechanical properties with eco-conscious formulation. Developed for high-performance textile and elastic coatings, it’s the ideal choice for manufacturers seeking a cost-effective, non-yellowing, and NMP, NEP, and DMAC-free solution.

With a solid content of 58–61%, SiwoPUD-2560 packs serious substance into every drop, allowing for thicker coatings that resist cracking even under stress. Its film boasts extraordinary elongation (1400–1500%), flexing effortlessly without sacrificing integrity. Need durability to match? It delivers with a tensile strength of 20.2 MPa and a 100% modulus of 0.8 MPa, offering the strength to endure wear and tear, while staying soft and flexible enough for dynamic applications.

Application-wise, SiwoPUD-2560 brings serious versatility. Its fast-drying, shear-stable, and non-volatile formulation lays down a tough, yet elastic film that resists heat, alkali, water, and abrasion—ideal for thick textile coatings that need to perform under pressure. Its translucent-white appearance, pH value of 7.0–9.5, and viscosity under 1500 mPa.s make it easy to handle and blend. And because it’s free from organotin compounds, formaldehyde, heavy metals, and other restricted substances, it fits seamlessly into safer, more sustainable production pipelines.

For enhanced durability and performance, SiwoPUD-2560 can also be paired with aziridine or water-dispersible polyisocyanate crosslinkers, tailoring the coating to even more demanding environments.

If you’re developing elastic, thick textile coatings that demand flexibility without compromising on toughness or sustainability, SiwoPUD-2560 brings the formula to the forefront—without the environmental trade-offs.
