Description
Product Overview
CHLUMICRYL® WPU-103 is a nonionic waterborne binder for finishing and sizing applications. The grade is supplied as a milky-white dispersion with pH 6-8 and is positioned for adhesion, initial tack, water resistance and solvent resistance. It can be screened in textile treatments, fabric-finishing systems and glass-fiber sizing formulations. Although the application profile overlaps with other nonionic grades, its specified pH and six-month storage period are distinct and should be preserved during product selection. Evaluate compatibility with processing auxiliaries and assess the finished treatment under its actual use conditions; stability across all acidic and alkaline formulations is not implied.
Grade Characteristics

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 finishing
- Fabric treatments
- Glass-fiber sizing formulations
Formulation and Handling
Verify compatibility with sizing ingredients and finishing auxiliaries.
Test stability at the actual formulation pH and processing conditions.
Review the current SDS before handling.
- Use the six-month storage period for this grade; do not substitute a twelve-month period from another resin.
- The material is a polyurethane dispersion, not a claim of complete molecular solubility.
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.
Packaging and Storage
50 kg or 120 kg plastic drums.
Store at 15-30 °C in a cool, dry, well-ventilated place. Protect from freezing and sunlight. Stated storage period: 6 months.
