SiwoPUD®-U-1529

When heat and adhesion are non-negotiable, U-1529 steps up. This aliphatic/polycarbonate polyurethane dispersion delivers a powerful trifecta: strong adhesion, high bond strength, and excellent heat resistance—making it the go-to solution for demanding industrial bonding applications.

With a solid content of 45%, U-1529 forms a high-build film that bonds with serious staying power. The film’s adhesion performance ensures long-lasting grip on challenging substrates like automotive interior components and magnetic cards, where heat, handling, and wear are part of daily life.

Unlike conventional dispersions that might degrade or delaminate under high temperatures, U-1529 is built for resilience. Its heat resistance makes it particularly suited for applications that face thermal stress, such as vehicle interiors that bake in the sun or plastic cards subjected to repeated swiping, bending, or thermal lamination.

Even better—U-1529 is NMP-free, meeting growing industry demands for safer, more sustainable chemistries without compromising on performance.

This product doesn’t just bond materials—it bonds performance with reliability. Whether you’re laminating functional layers, adhering complex composite parts, or creating specialty packaging that needs to stay intact under pressure, U-1529 keeps it together—literally and chemically.

Choose U-1529 when your application needs a polyurethane dispersion that can take the heat—and stay stuck through it all.
