Descrizione
Product Overview
CHLUMICRYL® WPU-7012 is supplied as a transparent liquid with a blue tint and is intended to form level, glossy films with useful extensibility. Its aliphatic polyurethane structure supports applications where film appearance and resistance to yellowing matter alongside flexibility. Target uses include leather surface finishing, paper treatment, heat-transfer printing and waterborne ink systems. The cationic character makes formulation compatibility an important selection step, especially when combining the resin with other emulsions or pigment dispersions. Confirm the required drying schedule, substrate adhesion, color stability and bending performance using the complete customer formulation.

Formulation and Handling
Screen compatibility before combining with other binders, pigments or additives.
Use substrate-specific trials to establish drying and application conditions.
- No numerical modulus is specified for this grade.
- Yellowing and bending performance depend on the formulation and exposure 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.
Imballaggio e stoccaggio
