Waterborne Polyurethane Resin TDD-600 - High Performance for Flexible Coatings
Product Overview
Waterborne Polyurethane Resin TDD-600 is a cutting-edge, grinding-and-film-forming integrated resin engineered for next-generation water-based inks and flexible coatings. Combining polyurethane’s inherent toughness with advanced aqueous dispersion technology, this resin delivers exceptional adhesion across diverse substrates, including PET, OPP, BOPA, and CPP films. As a 100% solvent-free solution, it enables infinite dilution with water and alcohols while maintaining outstanding water resistance, heat scalability, and rapid drying kinetics. Certified for food-contact applications and compatible with most acrylic systems, TDD-600 is the ideal binder for gravure and flexographic printing inks requiring non-blocking performance and long-term storage stability.

2. Process Parameters
- Grinding: 2–4h @2,000–3,000 rpm (horizontal bead mill, 0.3mm ZrO₂ beads).
- Filtration: 25μm sock filters for gravure; 100μm for flexo.
- Drying: 70–90°C air impingement; IR pre-drying optional.
Storage & Handling
1. Storage Conditions

- Above 40°C: Irreversible agglomeration; avoid thermal cycling.
- Critical notes:
- Environment:
- Ventilated, shaded area (UV exposure <5 kLux·hr/year).
- Sealed original containers to prevent:
- Water evaporation (viscosity increase >50%).
- Skin formation (maintain >80% relative humidity).
2. Shelf Life & Quality
- Guaranteed period: 6 months from production date (batch-code tracked).
- Post-thaw recovery:
- Gentle agitation @30–40°C for 24h (avoid high-shear mixing).
- Filter through 100μm mesh before reuse.
