SiwoPUD®-8051HB

When performance matters as much as appearance, SiwoPUD-8051HB steps up with a balanced formula built for durability, flexibility, and aesthetic integrity. This aqueous, aliphatic polyurethane dispersion based on polyether is supplied at 37% solid content in water, delivering a versatile, user-friendly option for fabric printing and textile coatings.

What sets SiwoPUD-8051HB apart is its fine-tuned chemistry. The coating film exhibits a unique blend of softness and excellent resilience, making it ideal for surfaces that need to flex, bounce back, and hold up under stress. With an impressive elongation range of 900–1000%, the material stretches with ease while maintaining form, supported by a tensile strength of 31.6 MPa and a 100% modulus of 3.1 MPa. Whether the end use is clothing, upholstery, or industrial textiles, this dispersion performs where others crack or fade.

Despite its strength, SiwoPUD-8051HB maintains a glass transition temperature (Tg) of -35°C, giving it outstanding low-temperature resistance—a key trait for environments where flexibility in cold conditions is non-negotiable. The shear stability is good, and the product offers quick processing times with dry-to-touch in ≤30 minutes and through-dry in ≤60 minutes. These fast curing times make it efficient in high-volume textile production or rapid prototyping environments.

For manufacturers concerned with visual integrity, SiwoPUD-8051HB delivers a translucent appearance and non-yellowing performance, preserving clarity and brightness over time. Its pH value between 7.0 and 9.5 ensures compatibility with a broad range of substrates and systems, and its mean particle size of ≤100 nm contributes to smooth, uniform coating formation.

Add to that its excellent water resistance and good washing fastness, and you have a coating solution built to last through wear, weather, and repeated laundering. This product contains 4.5% organic solvent, with no preservative added, and should be stored in a frost-free place in tightly sealed containers to maintain performance integrity.

Whether you’re upgrading textile durability or creating custom fabric coatings, SiwoPUD-8051HB is your next-generation solution—combining softness, strength, and environmental adaptability in every drop.
