SiwoPUD®-2453

When you need a coating that can stand up to the elements and stay beautifully resilient, SiwoPUD-2453 delivers. This aqueous, aliphatic polyurethane dispersion is engineered from polycarbonate diol and brings together a unique balance of power, clarity, and elasticity. Designed for demanding applications, it’s especially suited for elastic coatings and thick print coatings on fabric, where both mechanical strength and flexibility matter.

Formulated as a 50% non-volatile solid content dispersion in water, SiwoPUD-2453 is as stable as it is sustainable. It’s completely NMP-, NEP-, and DMAC-free, making it a safer choice for workers, the environment, and compliance with strict regulatory standards. Better yet, it contains no organotin compounds, formaldehyde, heavy metals, or other restricted substances under EU regulations.

What makes it stand out? Start with its incredible elongation of 950%, giving the film the flexibility to move without cracking or failing. Back that up with a tensile strength of 44.0 MPa and a 100% modulus of 2.2 MPa, and you’ve got a dispersion that doesn’t just stretch—it holds strong. Whether you’re applying it to fabric that needs to bend and flex or seeking a base for coatings that demand durability, this product can take the pressure.

The film it forms is translucent-white in appearance, non-yellowing, and dries fast, making it excellent for projects that need lasting clarity and speed in production. With good shear stability and a pH range between 6.5 and 8.5, it integrates seamlessly into a variety of formulation systems without losing consistency or stability. And with viscosity ≤600 mPa·s, it’s easy to process and apply across various industrial settings.

Whether you’re in textiles, elastomeric coatings, or specialty applications that require top-tier UV resistance, weather resistance, water resistance, and wear resistance, SiwoPUD-2453 checks every box. Add in an aziridine crosslinker or water-dispersible polyisocyanate crosslinker and you can push its performance even further—perfect for those who demand nothing but the best from their coatings.

With SiwoPUD-2453, you’re not just choosing a polyurethane dispersion—you’re choosing advanced performance, reliability, and compliance in every drop.
