Application:

Looking for a coating that bends without breaking and does it all without solvents? Meet PUD-1108—an aliphatic, polyether-based, non-ionic polyurethane dispersion that’s all about flexibility, softness, and environmental responsibility.

Formulated with no NMP and no organic solvents, PUD-1108 is ideal for applications demanding low-VOC or solvent-free solutions. It forms an exceptionally soft and flexible film, making it a go-to for sensitive substrates or uses where feel and freedom of movement matter more than mechanical stiffness.

But don’t let the softness fool you—this product can stretch. With an outstanding elongation of 1500%, PUD-1108 delivers unparalleled flexibility. It moves with the substrate, resisting cracking or failure even under extreme strain, making it suitable for stretchable textiles, breathable membranes, or delicate surface coatings where durability meets comfort.

Its solid content of 30±1% gives it excellent processability, while its non-ionic nature ensures stability across a wide pH range and compatibility with various systems. Because PUD-1108 is NMP-free, it meets increasing regulatory demands and sustainability goals in a world shifting toward greener chemistry.

If your coating application calls for soft touch, stretchability, and solvent-free peace of mind, PUD-1108 brings it all—without compromise.
