Application:

If your coating needs to level like a dream and hold up under pressure, PUD-1601 is your go-to solution. This aliphatic, NMP-free polyurethane dispersion is engineered with precision for surfaces that demand not only performance but finesse—especially in leather and dermal applications where appearance, flexibility, and durability go hand in hand.

With a solid content of 30±1%, PUD-1601 forms a lightweight yet strong film that offers exceptional leveling across complex surfaces. It lays down smooth, enhancing both the aesthetic and functional value of your finished product. Once dry, it delivers excellent adhesion, reliable water resistance, and strong hydrolysis resistance, ensuring the coating stays in place and performs long-term—even under tough conditions.

Let’s talk flexibility: With an elongation of 800–900%, a tensile strength of 29.5 MPa, and a modulus of 3.1 MPa, this dispersion offers a balanced combo of stretch and strength. It’s tough enough to resist cracking and splitting but soft enough to move with the material—especially valuable in applications that experience frequent bending or folding.

PUD-1601 also boasts good folding resistance at low temperatures, along with excellent dry and wet rub resistance—perfect for leather goods, accessories, or technical textiles that see daily handling.

If your product needs to stay smooth, stay strong, and stay flexible—PUD-1601 delivers with style.
