Water-based polyurethane dispersions (PUDs) are advanced eco-friendly materials extensively used in textile printing adhesives and synthetic leather production. These dispersions exhibit exceptional adhesion to diverse fabric substrates (cotton, polyester, nylon) and form flexible, durable films with high abrasion resistance and hydrolytic stability. Designed for low-VOC and formaldehyde-free formulations, they comply with stringent environmental regulations. Tailored viscosity profiles enable compatibility with screen printing, spraying, or coating processes, while aliphatic isocyanates (e.g., IPDI) ensure UV resistance and non-yellowing properties. For synthetic leather, PUDs integrate breathability, mechanical robustness, and customizable textures via foaming technology, meeting demands in automotive interiors, apparel, and accessories sectors.
Product Introduction
WL-PU230 is an aliphatic polyether polyurethane water-based dispersion with low viscosity, high elasticity, and good resistance to yellowing. It is suitable as the main resin for textile printing adhesives or water-based leather.

Properties
- Does not contain solvents such as NMP and DMAC, and does not contain organotin
- Soft film formation and good hand feel;
- Good elasticity, high elongation, elongation greater than 800%;
- Good washing fastness, no whitening after soaking in water for 48 hours;
- Excellent resistance to twists and turns.
Application
WL-PU230 is well-suited for use in outerwear jackets, bags, footwear uppers, and comparable applications. It functions as the principal resin in textile printing inks and can be adaptively combined with acrylic resins to accommodate customized formulation requirements.
Additionally, leveraging our technical proficiency, we develop tailored solutions and adjust formulations to comply with specified quality and performance benchmarks.
Storage Condition
This product should be stored in a sealed manner within the temperature range of 5 ℃ to 40 ℃. Under these conditions, the product can maintain stable performance for more than 6 months. The evaporation of water causes the film to no longer disperse. Please use it as soon as possible after opening.
