SiwoPUD®-806F

The Water-Resistant Powerhouse for Fabrics, Leather, and More

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 durability meets versatility, you get PUD-806F—a high-performance aliphatic polyurethane dispersion that’s built to last in tough, wet, and chemically challenging environments. Whether you’re developing waterproof textiles, leather goods, or printed fabrics that demand serious staying power, this one’s engineered to deliver.

With a solid content of 35±1%, PUD-806F forms a uniform, flexible film that balances durability with ease of application. Its film boasts excellent alkali resistance and superior water resistance, making it ideal for products exposed to moisture, cleaning agents, or outdoor conditions. From fashion materials and accessories to coated fabrics and specialty prints, this dispersion provides the shield your substrates need.

Its mechanical performance is equally impressive: a tensile strength of 12.7 MPa and a modulus of 2.7 MPa ensure the coating maintains integrity under stress. While slightly stiffer than ultra-elastic grades, it still provides a reliable degree of flexibility with an elongation of 500%—enough stretch to prevent cracking while staying strong under pressure.

The best part? It’s NMP-free, offering a safer, more eco-conscious formulation without compromising performance. That makes PUD-806F a perfect fit for environmentally driven brands seeking compliance with stringent regulatory standards.

If your application calls for high water repellency, chemical resistance, and robust physical performance, PUD-806F is the polyurethane dispersion that gets the job done—no compromise, no shortcuts.
