SiwoPUD®-1513F

When your materials need a soft finish with serious staying power, PUD-1513F steps in like a pro. This aliphatic polyurethane dispersion is all about flexibility and feel—perfect for surfaces that bend, stretch, and twist without breaking a sweat. It’s built to bond with challenging substrates like leather, PVC, PET, and other smooth surfaces where reliable adhesion matters most.

With a solid content of 33±1%, PUD-1513F lays down a light, breathable film that doesn’t feel heavy but holds its own. The secret sauce? Its crazy good elasticity. With elongation between 1300–1400%, it’s practically a yoga instructor—stretchy, resilient, and always bouncing back. Plus, with a tensile strength of 7.6 MPa and a super low modulus of 0.6 MPa, it’s flexible without being flimsy.

The film itself is soft, elastic, and ultra-smooth to the touch, making it ideal for applications in fashion accessories, flexible packaging, synthetic leather, or textile finishes that demand comfort and functionality. And since it’s NMP-free, you get high performance without the hassle of restricted solvents—great for sustainability-focused operations.

So whether you’re upgrading the feel of a leather product, working with complex films, or need a coating that flexes without failure, PUD-1513F is your go-to for softness that sticks.
