Beschreibung
Product Overview
WPU-6129 is a slightly yellow, transparent, viscous polyurethane resin intended for printing and laminating-ink development. It is supplied at 40 ± 2% solids and contains ethanol, making water/alcohol compatibility an important part of its formulation profile. The resin combines grinding and film-forming functions and is described as offering good printability and adhesion to PET and BOPP films. It may be evaluated where existing printing equipment or moderate drying capacity constrains process changes. Actual drying speed, ink stability and adhesion must be confirmed with the selected solvent balance, pigments, film treatment and press conditions.
Grade Characteristics
- Combined pigment-grinding and film-forming functions
- Water/alcohol compatibility
- Fast-drying formulation profile
- Printability and film adhesion for evaluation

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.
Anwendungen
- Waterborne printing and laminating inks
- Printing on PET films
- Printing on BOPP films
- Ink development for existing printing setups with limited drying capacity
Formulation and Handling
Use above 5 °C and keep the container sealed after each use.
Because the resin contains ethanol, obtain the current SDS and confirm ventilation, ignition-control and storage requirements before handling. Verify the stability of each selected water/alcohol ratio rather than assuming all finished formulations behave identically.
- The ethanol concentration and flash point are not specified in the available technical data; request current safety documentation.
- Water/alcohol compatibility and drying behavior must be checked in the complete ink 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.
Verpackung und Lagerung
50 kg or 120 kg plastic drums.
Store at 5-30 °C in a cool, dry, ventilated place, following the current SDS. Protect from freezing and direct light and reseal after use. Stated storage period: 6 months.
