Unobond FC is a high-performance, solvent-free, polyurethane adhesive that cures with humidity to form a strong, structural, and water-resistant bond. Its versatility and ease of use make it suitable for various applications in construction and marine environments.
Uses
- Bonding a wide range of building materials, including wood, plasterboard, particleboard, metal, foam, concrete, brick, masonry, and some plastics.
- Exterior woodwork and marine applications.
- Preventing floor squeaks by filling gaps and voids.
Benefits
- Superior bond strength for structural applications.
- One-component, no mixing required, simplifying the application process.
- Long open time allows for adjustments and repositioning.
- Fast-setting for efficient project completion.
- Extremely versatile, suitable for various substrates and environments.
- Resistant to high and low temperatures, ensuring performance in various climates.
- Highly water-resistant, ideal for damp and marine environments.
Application Guide
- Ensure surfaces are clean, sound, dry, even, and free from grease, laitance, loose particles, or other contaminants. Maximum humidity of the substrate should be 30%.
- Sand and solvent wipe non-ferrous metals.
- Priming is not usually required, but testing is recommended. Some non-porous surfaces may need Primer 50A.
- Apply a film of adhesive using a glue spreader, roller, or spray applicator at a rate of 7.5m2 - 10m2 per litre, ensuring enough adhesive to contact both surfaces when pressed together.
- Immediately bring substrates together and clamp, nail, or screw to apply even pressure for about 1.5 hours.
- Maintain contact between surfaces during curing.
Limitations
- Reduced strength when used as a gap filler.
- Requires pressure during curing to achieve maximum strength.
Remarks
- Unobond FC slightly expands during curing, filling irregularities in the substrate.
- For flooring applications, follow the flooring manufacturer's specifications.
