When flexibility, resilience, and environmental safety are non-negotiable, SiwoPUD-2456 delivers on every front. This aqueous, aliphatic polyurethane dispersion is built on a foundation of polyether diol, offering the perfect balance of softness and performance. With a 50±1% non-volatile solid content, this translucent-white dispersion is easy to work with and designed to dry fast—making it a reliable option for demanding coating applications that don’t compromise on finish or feel.
Unlike conventional dispersions, SiwoPUD-2456 contains no NMP, NEP, or DMAC, and is entirely free of organotin compounds, heavy metals, and formaldehyde, making it a safe and compliant choice for manufacturers in the EU and global markets. Whether you’re formulating for synthetic leather, fabric printing, thick coatings, or elastic applications, this PUD offers impressive compatibility without compromising environmental standards.
What truly sets SiwoPUD-2456 apart is its exceptional mechanical profile. With an elongation capacity of 2000%, it flexes with extreme ease—ideal for substrates and coatings that need to move. Add in a tensile strength of 17.5 MPa and a low 100% modulus of 0.76 MPa, and you get a soft film that’s also durable and stress-resistant. Its excellent hydrolysis and alkali resistance make it an ideal choice for performance fabrics and long-wear materials.
The formulation features good shear stability and is non-yellowing, so it maintains its clarity and integrity over time. For manufacturers looking to push the performance envelope even further, aziridine or water-dispersible polyisocyanate crosslinkers can be introduced to amplify strength and resilience.
From elasticity to environmental compliance, SiwoPUD-2456 is the advanced polyurethane dispersion that checks all the right boxes.
