Product Overview
CHLUMICRYL® WPU-7013 is a cationic polyurethane dispersion with an acidic pH range and a transparent, blue-toned liquid appearance. It is intended as a binder for waterborne inks, leather finishing, transfer printing, and paper surface treatments. Film smoothness, gloss, extensibility and resistance to yellowing are the principal formulation targets. When selecting this grade, assess the complete coating or ink rather than relying only on liquid solids and viscosity. Ionic compatibility, pigment incorporation, substrate preparation and drying conditions can affect stability and final performance. Trial batches should establish the required appearance and mechanical properties before scale-up.
Grade Characteristics
- Smooth, glossy film formation
- Extensibility and bending resistance

- Pen and inkjet ink formulations
- Paper surface treatment
Formulation and Handling
Check compatibility with pigments, additives and other binders before mixing.
Verify film appearance and mechanical performance after drying under the intended production conditions.
- No numerical modulus or pencil-hardness value is offered for grade selection.
- Confirm performance requirements and test methods for the finished formulation.
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.
