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.
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.
