Unobond Polyurethane Adhesive 310ml

Unobond 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.
• Fast-setting for efficient project completion.
• Extremely versatile, suitable for various substrates and environments.
• Resistant to low temperatures, ensuring performance in cold conditions.
• Highly water-resistant (D4 classification), ideal for damp and marine environments.

Application Guide

1. Ensure surfaces are clean, dry, even, and free from grease and contaminants.
2. Apply a bead of Unobond using a cartridge gun.
3. Immediately bring the substrates together and apply pressure by clamping, nailing, or screwing for approximately 30 minutes.
4. Maintain consistent pressure across the entire surface during curing.
5. For flooring applications, follow the flooring manufacturer's specifications.

Limitations

• Reduced strength when used as a gap filler.
• Requires pressure during curing to achieve maximum strength.

Remarks

• Surfaces must be clean, sound, free from dirt, grease, laitance, loose particles or other contaminates and should have a maximum humidity of 30%.
