SiwoPUD®-FB145

When your coating needs to bend without breaking—and bounce back better than ever—PUD-FB145 is built to deliver. This aromatic, polyether-based polyurethane dispersion combines softness with high elasticity, making it the go-to solution for applications that demand resilient stretch, reliable durability, and resistance to the elements.

Engineered with a solid content of 45±1%, PUD-FB145 forms films that are both substantial and flexible, without sacrificing ease of application. Its mechanical profile is impressive: with an elongation range of 1400–1500%, this dispersion offers extraordinary stretch—ideal for substrates that undergo frequent bending, flexing, or compression. Add in a tensile strength of 36.7 MPa and a 100% modulus of 1.9 MPa, and you’ve got a coating that’s not just flexible, but also tough enough to stand up to daily wear.

One of its standout features? It’s NMP-free, giving manufacturers a safer, more environmentally responsible option without compromising on performance.

But what truly sets PUD-FB145 apart is its versatility. Its coating is easy to foam, making it an excellent choice for the base layer of synthetic leather, where softness and structure are both essential. Whether you’re working with footwear, upholstery, or flexible composites, this PUD provides a strong, stretchable foundation. On top of that, it offers excellent water resistance and strong alkali resistance, enabling long-term durability even in chemically challenging environments.

So, whether you’re looking to build up a breathable leather base, create cushion-like layers, or develop a flexible product that won’t back down under pressure, PUD-FB145 is ready to perform.

Soft. Stretchy. Strong. Foam-friendly. This is next-level polyurethane dispersion—engineered for when flexibility is just the beginning.
