SiwoPUD®-F122

When your application demands a balance of durability, flexibility, and surface adhesion, SiwoPUD-F122 delivers with precision. This aqueous, aromatic polyurethane dispersion based on polyester is engineered for coatings that need to perform under pressure—especially on materials like PVC, rubber, and leather.

Supplied at a 33% non-volatile solid content, this dispersion offers a light yellow translucent appearance, low viscosity (≤50 mPa·s), and exceptional formulation flexibility. With a mean particle size of ≤100 nm, SiwoPUD-F122 ensures smooth film formation and consistent coverage, even on complex or irregular surfaces. It’s entirely NMP, NEP, and DMAC-free, making it a safer, more environmentally conscious option in production lines where health and sustainability are a concern.

In terms of performance, the coating formed by SiwoPUD-F122 is in the sweet spot of medium hardness—tough enough to resist wear, yet flexible enough to conform to a range of substrates. Its elongation capacity of 450–550% means it can flex without cracking, while its impressive tensile strength of 24.1 MPa and 100% modulus of 7.2 MPa give it the mechanical integrity needed for high-performance finishes.

Speed matters in production—and SiwoPUD-F122 doesn’t disappoint. It features a dry-to-touch time of ≤30 minutes and a full-through dry time of ≤60 minutes, helping manufacturers stay on schedule without compromising quality. The formulation offers good shear stability, supporting smooth processing during application and ensuring consistency in output.

With a pH range of 7.5–9.5, this dispersion is stable and adaptable, and it maintains its integrity during storage when kept in tightly sealed containers in frost-free environments. Note: this product contains no preservative, so appropriate storage is essential.

If you need a polyurethane dispersion that grips PVC, rubber, or leather with tenacity while offering production-ready flexibility and performance, SiwoPUD-F122 is your next formulation essential.
