Use Unobond Polyurethane Adhesive for: Structural bonding, marine-grade adhesion, exterior timber work, and water-resistant applications

Unobond is a premium-grade, solvent-free polyurethane adhesive engineered for superior structural bonding. It cures through humidity exposure and delivers a D4-classified waterproof bond suitable for demanding applications, including marine environments and exterior timber work. With strong adhesion to a wide array of substrates—from timber and metal to foam and masonry—Unobond is a versatile choice for Australian trade professionals across building, joinery, marine, and civil construction sectors.

Primer Information: No primer required for most surfaces; ensure one surface contains moisture for optimal curing. Test recommended for plastic substrates.

Cure Time: Skins in 10 minutes, initial set in 30 minutes, full strength achieved after 24 hours. Clamp, nail, or screw for the first hour to ensure surface contact.

Coverage Rate: 120–250g per m² depending on surface porosity and application technique. Slight expansion helps fill minor gaps and surface irregularities.

Application Temperature Range: +5°C to 35°C (41°F to 95°F), ideal for varied Australian climates from coastal to inland regions.

Chemical Properties: Solvent-free polyurethane. Resistant to moisture, cold temperatures (down to -30°C), and heat (up to 100°C). Uninflammable and sensitive to ambient humidity which accelerates curing.

Key Features of Unobond Polyurethane Adhesive

  • Solvent-free formulation ensures safer use with no VOC emissions.
  • Fast-setting time (initial set in 30 minutes) saves time on-site.
  • Classified D4 for water-resistant bonding, ideal for marine and wet areas.
  • Expands to fill voids, reducing squeaky floors and improving substrate contact.

Why Choose Unobond Polyurethane Adhesive:

  • Outstanding adhesion to nearly all construction materials used in Australia.
  • No mixing required—simply apply and clamp for high bond performance.
  • Performs in cold climates, coastal conditions, and humid environments.
  • Tested tear resistance up to 130kg/cm² and tensile strength of 5N/mm².

Frequently Asked Questions About Unobond Polyurethane Adhesive

Q: What materials can Unobond bond?

A: Unobond bonds to wood, plasterboard, particleboard, aluminium, iron, steel, sheet metal, polystyrene foam, insulation foam, concrete, FC sheeting, brick, masonry, veneer, melamine, and many plastics (testing recommended).

Q: Is Unobond suitable for outdoor use?

A: Yes, Unobond is suitable for exterior woodwork and marine environments due to its high water resistance (D4 classification).

Q: How long does Unobond take to cure?

A: Unobond has a skinning time of 10 minutes, an initial set of 30 minutes, and achieves full strength in 24 hours.

Q: Do I need to mix Unobond before application?

A: No, Unobond is a one-component adhesive that requires no mixing.

Q: How do I apply pressure during curing?

A: Apply pressure using clamps, nails, or screws for about 30 minutes to achieve maximum strength.

Use Unobond Polyurethane Adhesive for:

  • Structural bonding of wood, metals, and plastics.
  • Exterior woodwork and marine applications.
  • Bonding diverse materials in construction and manufacturing.
  • Flooring applications (follow manufacturer's specifications).
  • General-purpose bonding requiring high water resistance.

Why Use Unobond Polyurethane Adhesive:

  • Provides superior bond strength and water resistance.
  • Quick-setting and easy to apply with no mixing required.
  • Versatile for a wide range of materials and applications.
  • Suitable for demanding environments, including marine.
  • Enhances bonding with slight expansion to fill gaps.

How to apply Unobond Polyurethane Adhesive:

  1. Prepare the surfaces: Ensure they are clean, dry, and free from grease.
  2. Apply the adhesive: Use a cartridge gun to apply a bead of Unobond.
  3. Bond the materials: Bring the substrates together immediately.
  4. Apply pressure: Clamp, nail, or screw the materials together for about 30 minutes.
  5. Clean up: Remove excess adhesive before it cures.

Unobond Polyurethane Adhesive limitations:

  • Reduced strength when used as a gap filler.
  • Requires pressure during curing for maximum strength.
  • Surfaces should have a maximum humidity of 30%.

Safety precautions when using Unobond Polyurethane Adhesive:

  • Personal Protective Equipment: Wear gloves and eye protection.
  • Ventilation: Ensure adequate ventilation during application.
  • Handling: Avoid skin and eye contact. Wash hands after use. Consult the SDS for detailed safety information.
  • First Aid: For skin contact, wash with soap and water. For eye contact, flush with water. If ingested, seek medical advice.

Unobond Polyurethane Adhesive can be used on the following substrates:

  • Wood (ensure clean and slightly moist).
  • Plasterboard and particleboard (clean and dry).
  • Aluminium, iron, steel, and sheet metal (clean and free from grease).
  • Polystyrene foam and insulation foam.
  • Concrete, FC sheeting, brick, and masonry (clean and free from loose particles).
  • Veneer and melamine (ensure clean surfaces).
  • Many plastics (testing recommended for compatibility).
