Application:

Need a coating that knows how to keep things smooth without dialing down performance? Meet PUE-991F, the softer sibling of PUE-990F that still holds its own when it comes to durability and flexibility. This aliphatic, NMP-free polyurethane dispersion is tailored for fabric coatings and heat transfer printing, where both feel and function matter.

With a solid content of 45±1%, PUE-991F delivers full-bodied coverage perfect for thick coatings on textiles. It offers a nice, soft film that doesn’t compromise on the good stuff—elongation between 650–750%, a tensile strength of 8.9 MPa, and a 100% modulus of just 1.5 MPa. That means it stretches beautifully, stays soft to the touch, and still resists cracking, fading, and peeling like a champ.

The charm of PUE-991F lies in its versatility. Whether you’re crafting athletic wear with bold prints or creating large-format graphics that need to transfer clean and clear, this dispersion offers a smooth application, excellent bonding, and strong resistance to water, heat, and wear.

It performs beautifully under pressure—literally—and gives you the kind of long-lasting, premium finish that sticks around without getting stiff. If your end product needs that soft hand feel but also demands top-tier durability, PUE-991F is your go-to formula.

So go ahead, print bold, press hard, and coat confidently—PUE-991F has your back.
