Description
Product Overview
CHLUMICRYL® WPU-5130 is a waterborne polyurethane binder for coatings that need a hard film and resistance to water, yellowing and thermal exposure. It is supplied as a translucent liquid at pH 7-9. The product information highlights smoothness, gloss and adhesion, together with resistance to toluene. A reported warm-water exposure result can guide laboratory screening, but it does not replace qualification of the finished coating. Formulators should establish substrate preparation, drying and film thickness before evaluating resistance. No numerical hardness or continuous service-temperature rating is assigned, so selection should rely on application-specific testing rather than a broad performance guarantee.
Grade Characteristics
- Hard-film coating profile
- Water and toluene resistance profile

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
- Protective coatings requiring water resistance
- Coatings requiring resistance to yellowing
- Coating development involving thermal exposure
Formulation and Handling
Qualify the dried film under the actual water, solvent and temperature exposure conditions.
Confirm compatibility with other binders and additives before production.
Review the current SDS before handling.
- Product information reports no whitening after one hour in 60 °C water; film thickness, curing conditions and the full test method are not specified. Verify this performance in the finished coating.
- Hard film character is qualitative, and no continuous service-temperature rating is given.
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 5-35 °C in a cool, dry, well-ventilated place. Protect from freezing and sunlight. Stated storage period: 12 months.
