Description
Product Overview
WPU-8081 is a slightly yellow, translucent polyurethane dispersion with 35 ± 2% solids. Its application profile centers on printed textiles, inks and genuine-leather finishing where a soft, full coating feel and an even glossy surface are desired. The reported tensile strength is 35-45 MPa, alongside a 100% modulus of 5-7 MPa and elongation at break of 600%. These values help distinguish its film profile during grade selection. Evaluate the complete pigmented formulation and drying process to establish practical hand, flexibility, adhesion and print appearance on the intended fabric, film or leather substrate.
Grade Characteristics
- Soft, smooth film formation
- Glossy appearance
- Full hand
- Good film extensibility

These values are technical selection data, not a batch-specific certificate of analysis. Test methods, current specifications and any acceptance limits should be confirmed before ordering.
Applications
- Textile printing pastes
- Waterborne printing inks
- Genuine-leather surface treatments
Formulation and Handling
Evaluate pigment and additive compatibility before scale-up. Verify the desired coating hand and adhesion on the final substrate after the selected drying and conditioning process.
- The 600% elongation value is reported without a minimum symbol or tolerance; it is not stated as a guaranteed lower limit.
- Mechanical comparison requires consistent film preparation and test conditions.
Check binder compatibility, substrate preparation, application conditions and final coating or bond performance in your own formulation. Waterborne use does not by itself establish solvent-free status or a hazard classification. Consult the current safety data sheet and use appropriate industrial handling controls.
