Application:

If you loved what PUD-805F could do, you’re about to fall for PUD-8051F—the softer, smoother evolution of its high-performance sibling. This aliphatic, NMP-free polyurethane dispersion keeps all the strength and resilience of the original but turns up the comfort, delivering an ultra-soft feel without sacrificing durability.

With a solid content of 35±1%, PUD-8051F forms a beautifully flexible, elastic film that’s ideal for fabric printing, leather finishing, and other soft-touch applications. It’s engineered for stretch—with an elongation of up to 1500%, this coating bends and moves effortlessly while maintaining shape. Add a tensile strength of 33.7 MPa and a modulus of 1.15 MPa, and you’ve got the perfect combination of gentle flexibility and quiet strength.

What sets PUD-8051F apart is its enhanced softness, making it a favorite for garments, upholstery, or technical fabrics where the hand-feel matters just as much as long-term performance. It’s also highly resistant to wear, weather, and chemical exposure—perfect for everyday use and extreme environments alike.

Like its predecessor, it boasts excellent water fastness, peel strength, and folding resistance, especially in low temperatures. And because it’s NMP-free, it’s a smarter, safer choice for modern manufacturing needs.

Bottom line? PUD-8051F is all about giving your coated fabrics and leathers that premium soft finish—without losing the toughness that keeps them going strong.
