SiwoPUD®-2308

When performance and cost-efficiency matter, SiwoPUD-2308 delivers. This aqueous, aliphatic polyurethane dispersion based on polyether combines a highly elastic film with outstanding environmental stability, making it an excellent choice for applications where flexibility and water resistance are key.

With a solid content of 35±1%, SiwoPUD-2308 creates a smooth, durable film with excellent stretch. Its mechanical properties are impressive: the film boasts elongation between 900–1000%, tensile strength of 17.4 MPa, and a 100% modulus of 1.6 MPa, giving it the strength to perform under stress without compromising softness or adaptability. Whether applied to flexible substrates or demanding surfaces, this formulation ensures a resilient, long-lasting finish.

One of the key advantages of SiwoPUD-2308 lies in its stability and safety. It is organic solvent-free, with no added preservatives, and features a pH value between 6.0–7.5, making it both user- and environmentally friendly. The viscosity is ≤200 mPa·s, ensuring easy handling and smooth application across a variety of systems. Thanks to a mean particle size ≤100 nm and non-ionic ionicity, this dispersion offers excellent compatibility with anionic and cationic aqueous polyurethane dispersions as well as other ionic water-based resins, giving formulators the flexibility to fine-tune their systems without sacrificing stability.

Designed with modern performance standards in mind, SiwoPUD-2308 excels in hydrolysis resistance, water resistance, and shear stability. It also maintains a glass transition temperature (Tg) of -35°C, ensuring flexibility in cold conditions. And unlike many polyurethane dispersions, SiwoPUD-2308 is non-yellowing, preserving the clarity and aesthetics of your final product.

Whether you’re formulating coatings for textiles, films, or specialty industrial surfaces, SiwoPUD-2308 offers the right balance of economy, durability, and environmental safety. Store it in frost-free, tightly sealed containers, and let this next-gen polyurethane dispersion elevate your coating systems with ease.
