UCECOAT® 7999

UCECOAT® 7999 is a bio-based energy-curable polyurethane dispersion developed as a binder for clear and pigmented coatings. Here's a breakdown of its key features and properties as outlined in the provided technical datasheet:

Type:
Bio-based energy curable polyurethane dispersion.

Introduction:
UCECOAT® 7999 is described as a low-viscosity, high-performance dispersion made from renewable feedstocks. It contains approximately 22% bio carbon and contributes to a reduction in the material carbon footprint. The product is solvent-free, tin-free, and APEO-free, making it regulatory compliant.

Performance Highlights:

• Offers superior protection as a binder for water-based clear and pigmented coatings.
• Good colloidal stability, even in the presence of pigments and additives.
• Tack-free after water evaporation and before cure.
• Low Minimum Film Formation Temperature (MFFT) that eliminates the need for additional coalescing agents.
• Physically drying with good reactivity upon radiation curing.
• Cured coating exhibits immediate optimum hardness without requiring oxidative drying.
• Provides excellent chemical and mechanical resistance while maintaining flexibility for good dimensional stability and adhesion.

Suggested Applications:
Can be applied by spray application or other coating methods such as gravure, flexography, screen, curtain, or immersion. Suitable for covering natural or coated wood, plastics and PVC flooring, paper and paperboard, leather and textile, or concrete substrates.

Typical Wet Properties:

• Appearance: Translucent, pale yellow
• Solid Content: 33 - 35%
• Brookfield Viscosity at 25°C: < 200 mPa.s
• pH: 7.0 – 8.5
• Mean Particle Size: < 100 nm
• Minimum Film Formation Temperature: ≤ 5°C
• Stability at 60°C: ≥ 10 days

Sustainability Positioning:
Aligned with the corporate sustainability commitment to pursue a greener and sustainable future.

Storage and Handling:

• Shelf life: Not more than 1 year.
• Recommended storage temperature range: Between 4°C and 40°C (39°F to 104°F).
• Avoid exposure to high temperature or direct sunlight to prevent product destabilization.
• Handle with care to avoid pressure build-up in the container.
• Consult the Safety Data Sheet for detailed safety and handling procedures.

UCECOAT® 7999 offers a sustainable and high-performance option for water-based coatings, contributing to environmental responsibility while providing excellent coating properties.
