Soft, Strong & Super Resilient—Made for Fabrics That Flex

Characteristics:

Aqueous, aliphatic polyurethane dispersion based on polyether.

Supplied as:

35% in water

Storage:

The dispersion should be stored in a frost-free place in tightly sealed containers. It contains no preservative.

Application:

When your coating needs to feel soft but fight like a heavyweight, PUD-805F is the perfect pick. This aliphatic polyurethane dispersion is crafted for applications that call for comfort, flexibility, and durability—think fabric printing, leather finishing, and technical textiles that need to move and hold up under stress.

With a solid content of 35±1%, PUD-805F delivers rich coverage and a smooth application. The final film? It’s soft and elastic, built with excellent resilience so it can stretch, fold, and bounce back—no cracking, no flaking. Its elongation range of 1100–1200% means it’s super stretch-friendly, while a tensile strength of 35.4 MPa and 100% modulus of 1.76 MPa give it real muscle beneath that soft touch.

But that’s just the start. PUD-805F brings top-notch alkali resistance, making it ideal for garments or substrates exposed to harsh environments. It’s got impressive water fastness, strong peel strength, and great folding resistance even at low temperatures—perfect for performance fabrics, outerwear, or leather products designed for all-season use.

The cherry on top? It’s NMP-free, keeping your formulations clean, compliant, and forward-thinking.

So if you’re looking for a coating that’s gentle on the touch but tough under pressure, PUD-805F is your fabric’s best friend.
