Lihat Profil SellerTwo-component polyester polyurethane adhesive for high-performance lamination of films and foils
NOVACOTE NC-825-A with co-reactant CA 26 is a high-performance, two-component polyester polyurethane adhesive system engineered for the lamination of diverse film and foil substrates. Known for its excellent chemical resistance and durability, this adhesive delivers strong initial bonds that remain stable after curing, making it ideal for demanding industrial applications. It performs exceptionally well under heat pasteurization and retort conditions, ensuring long-term laminate integrity. The clear, low-viscosity formulation enables easy application and uniform coverage, while compatibility with substrates such as PET, BOPP, OPA, aluminum foil, metallized films, and coated cello enhances its versatility across flexible packaging, labeling, and pharmaceutical applications. Compliant with food contact regulations, including 21 CFR 175.105, it is suitable for use in food packaging where safety and reliability are critical.
Specifications
- Mixing Ratio (by mass): 100 : 20 (NC-825-A : CA 26) (Manufacturer Recommendation)
- Recommended Solvents: Ethyl acetate (urethane grade), MEK (H₂O <0.05%), Acetone (Processing Guidelines)
- Drying Temperature (Web): 50–65°C (Typical Lamination Conditions)
- Nip Temperature (Optional): 40–60°C (For improved wetting and clarity)
- Curing Time (Full Chemical Resistance): 7–10 days at room temperature (Standard Industry Practice)
- Rewind/Slitting Time: Several hours after lamination (Practical Handling Guideline)
- Viscosity: Low (Visual/Process Observation)
- Appearance: Clear (Visual Inspection)
Applications
- Flexible food and beverage packaging
- Pharmaceutical blister and pouch packaging
- Laminated labels and decorative films
- Retortable and sterilizable packaging
- Aluminum foil laminations
- Metallized film composites with CPP/LLDPE
Advantages
- High initial bond strength with stable performance after curing
- Excellent resistance to heat, pasteurization, and retort processes
- Superior chemical resistance to aggressive solvents and filling goods
- Clear appearance for aesthetic final products
- Low viscosity for easy application and uniform coating
- Compatible with a wide range of film and foil substrates
- Suitable for food contact applications per FDA regulations
Processing Conditions
- Mix ratio: 100 parts NC-825-A to 20 parts CA 26 by weight
- Use urethane-grade ethyl acetate, MEK (moisture <0.05%), or acetone as solvent
- Dry web to 50–65°C for complete solvent evaporation
- Ambient temperature lamination reduces curling; warm nips (40–60°C) improve adhesion and clarity
- Ensure proper ventilation due to isocyanate and solvent content
Regulatory Compliance
- FDA 21 CFR 175.105 (Adhesive components for indirect food contact)
- Complies with general foodstuff legislation for packaging materials
Packaging Information
- Supplied in two components: NC-825-A and CA 26
- Typical packaging: Drums or pails (exact size may vary by region)
Storage Conditions
- Store in original containers, tightly closed, in a cool, dry, and well-ventilated area
- Protect from moisture and direct sunlight
