Description
Product Overview
CHLUMICRYL® WPU-3300 is intended as a film-forming resin for specialty top finishes and coatings where clarity and toughness are priorities. Its application profile includes high-performance inks, specialty coatings and non-peelable nail-coating formulation development. The film is designed to support adhesion, wet and dry rub resistance, cut resistance and scratch resistance. The product contains a bio-based component, without a specified certified content level. For any cosmetic end use, the complete formulation and ingredient documentation require a separate safety and regulatory assessment. Keep the resin isolated from curing agents during storage and establish compatibility before formulation.
Grade Characteristics
- Clear, tough film formation
- Adhesion to support coating durability
- Wet and dry rub, cut, solvent and scratch resistance
- Contains a bio-based component

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
- Specialty topcoats
- High-performance ink binders
- Tough protective coating formulations
- Non-peelable nail-coating development, subject to end-use assessment
Formulation and Handling
Avoid direct contact with curing agents during storage.
Check compatibility, application method and drying conditions in a trial formulation.
For cosmetic applications, obtain the required ingredient documentation and assess the finished formulation before use.
- The bio-based proportion is not specified; no biodegradability or certified bio-based claim is made.
- Adhesion and flexibility figures require an agreed test standard before comparison with other products.
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 2-25 °C in a cool, dry, well-ventilated place. Protect from freezing and light, and keep away from direct contact with curing agents. Stated shelf life: 12 months.
