Lihat Profil SellerTwo-Component Polyester Polyurethane Laminating Adhesive for High-Performance Film Bonding
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 substrates. Renowned for its excellent chemical and heat resistance, this adhesive delivers strong initial bond strength that further develops post-cure, ensuring long-term laminate integrity. It is especially suited for applications involving aggressive fillers, retort processing, and high-temperature pasteurization. Compatible with PET, BOPP, OPA, aluminum foil, metallized films, coated cellophane, CPP, and LLDPE, the clear adhesive maintains optical clarity and aesthetic appeal in final packaging. With a recommended mixing ratio of 100:20 (NC-825-A:CA-26) and adjustable viscosity via ethyl acetate, MEK, or ethanol, it offers flexible processing for industrial efficiency. Compliant with key FDA regulations for indirect food contact, it is widely used in food, pharmaceutical, and electronics packaging where safety and durability are critical.
Specifications
- Mixing Ratio (NC-825-A : CA-26): 100:20 by mass (Manufacturer Recommendation)
- Viscosity at 25°C: 13–26 Dinn-Cup seconds (Dinn-Cup, depending on solids content)
- Solvent Compatibility: Ethyl acetate (urethane grade), MEK (H₂O <0.05%), Ethanol (Processing Guideline)
- Curing Characteristics: Strong initial bond with continued strength development after cure (Bond performance evaluation)
- Heat Resistance: High; suitable for pasteurization and retort processes (Thermal stability testing)
- Substrate Compatibility: PET, BOPP, OPA, Aluminum Foil, Metallized Films (CPP, LLDPE), Coated Cello (Adhesion testing on various films)
Applications
- Food packaging lamination (retortable pouches, stand-up bags)
- Pharmaceutical blister and barrier packaging
- Electronics protective film lamination
- Industrial flexible packaging requiring chemical resistance
- High-barrier laminates for harsh environments
Advantages
- Exceptional resistance to aggressive chemicals and filling goods
- Maintains bond strength under high-temperature sterilization (retort & pasteurization)
- Clear appearance ensures no discoloration or haze in final product
- Strong initial adhesion with progressive post-cure strength development
- Broad substrate compatibility across plastic, metallic, and composite films
- Flexible processing with standard solvents and adjustable viscosity
Processing Conditions
- Mixing ratio: 100 parts NC-825-A to 20 parts CA-26 by weight
- Use urethane-grade ethyl acetate, MEK (moisture <0.05%), or ethanol as diluents
- Apply and dry to achieve desired coating weight before lamination
- Ensure proper curing time and temperature based on end-use requirements
- Recommended for use in controlled humidity and temperature environments
Regulatory Compliance
- FDA 21 CFR 175.105 (Indirect Food Contact – Adhesives)
- FDA 21 CFR 177.1390 (Polyurethane Resins – IV compliant)
- Complies with general food packaging safety standards (non-direct contact)
Packaging Information
- Available in 20 kg, 200 kg drums, or bulk containers
- Co-reactant CA-26 typically supplied in smaller moisture-resistant packaging
Storage Conditions
- Store in original, tightly sealed containers
- Keep in a cool, dry place below 25°C
- Protect from moisture, heat, and direct sunlight
- Shelf life: Typically 6–12 months for NC-825-A; CA-26 has shorter shelf life (~3–6 months) due to reactivity
Safety Information
- Use personal protective equipment (gloves, goggles, respirator) when handling uncured adhesive
- Avoid skin and eye contact; isocyanates in CA-26 can cause sensitization
- Store and process in low-moisture environments to prevent premature reaction
- Refer to SDS for first aid, spill response, and disposal procedures
