Application:

Some coatings are all about toughness—PUD-1512 is all about the feel. This aliphatic polyurethane dispersion brings a unique combo of softness, elasticity, and a touch of tack, making it the ideal choice when surface grip and flexibility are key. Think leather, PVC, PET, and other smooth substrates that need a coating that can hold on without letting go.

With a solid content of 35±1%, PUD-1512 delivers excellent film formation and build, while staying lightweight and easy to work with. The numbers don’t lie—elongation ranges from 900–1000%, meaning this film can stretch to the max and bounce back without breaking a sweat. Its tensile strength of 10.6 MPa and modulus of 1.2 MPa strike a balance between gentle flexibility and functional durability.

The slightly sticky finish isn’t a flaw—it’s a feature. That subtle tack gives PUD-1512 an edge in grip-sensitive applications, helping improve bonding on trickier substrates. Whether it’s for fashion leather goods, flexible film packaging, or custom coatings that need to move, stretch, and stay connected, this one’s got the vibe.

And while it does contain NMP, its performance makes it a top-tier pick for niche applications that demand feel, form, and function—all in one.

So if you’re after a polyurethane dispersion that hugs the surface with softness and serious stretch, PUD-1512 is your go-to.
