SiwoPUD®-808F-35

When performance matters—down to the very last detail—SiwoPUD-808F-35 steps up as the smart, sustainable solution for advanced coating applications. This aqueous, aliphatic polyurethane dispersion is based on polyether chemistry, delivering the ideal blend of flexibility, strength, and long-term stability for demanding surfaces like leather and fabric.

From the moment it’s applied, SiwoPUD-808F-35 starts to show what it’s made of. The translucence-white appearance forms a soft yet resilient film with standout qualities that elevate the finish. With an impressive elongation of 1100–1200% and tensile strength of 51.9 MPa, it stretches without stress—then bounces right back. Combined with a 100% modulus of 2.6 MPa, this product holds its own in environments where both strength and flexibility are non-negotiable.

Fast-drying and shear stable, this dispersion is a top choice for high-throughput production lines where consistency matters. Its non-yellowing performance ensures a clean, professional finish over time, even under UV exposure or prolonged use. And if your application demands resistance to tough conditions, you’ll appreciate its excellent alkali resistance, superior water resistance, and reliable low-temperature folding endurance—key for products exposed to moisture, movement, or environmental stress.

In terms of formulation safety, SiwoPUD-808F-35 is as forward-thinking as it gets. It’s completely NMP, NEP, and DMAC free, contains no organotin compounds, heavy metals, formaldehyde, or EU-restricted substances, and remains stable in frost-free storage without the need for preservatives.

Ideal for fabric and leather coatings, this dispersion is versatile and customizable. Additives like aziridine, carbodiimide, or water-dispersible polyisocyanate crosslinkers can be introduced to boost performance even further—making it the adaptable solution for specialized coating challenges.

If you’re looking for a polyurethane dispersion that goes beyond the basics—with safety, strength, and sustainability baked in—SiwoPUD-808F-35 delivers, from start to finish.
