High strength polyurethane sealant and adhesive

(310ml EU3 cartridge available in a choice of colours)

Excellent primerless adhesion to most materials

Versatile, high-strength polyurethane adhesive and sealant with excellent adhesion, producing tough, flexible joints with resistance to oil, water and most chemicals. Ideal for sealing expansion joints and suitable for overpainting with water-based and most solvent-based paints.

Creates a very strong bond between a wide range of materials. Thanks to its elasticity, PU18 is particularly effective where movement or vibration is likely to occur, making it ideal for vehicles, boats, trailers, machinery and other demanding applications. Its tough, elastic seal helps dampen vibration, making it a favourite of the construction, engineering and transport industries.

PU18 bonds to a wide range of materials, including concrete, brick, stone, wood, metals, aluminium, glass, ceramics, GRP, polyester, PVC and rubber.

Features & Benefits

• High-strength - forms strong, durable bonds and tough, flexible seals
• Excellent primerless adhesion - bonds to concrete, brick, stone, wood, metals, GRP, glass, ceramics, PVC, rubber and many common building materials
• Flexible & vibration damping - produces tough, elastic joints that absorb movement and help reduce vibration
• Oil & chemical resistant - resistant to oil, water, seawater, diluted alkalis, cement grout and water-based detergents
• Interior & exterior use - suitable for construction, engineering, automotive and marine applications
• Overpaintable - can be painted with water-based paints
• Expansion joint suitable - ideal for sealing expansion joints in brickwork with movement up to 15%
• Wide service temperature - remains flexible from -30°C to +80°C after curing

Did you know? Flexible polyurethane adhesives help damp vibration by absorbing movement within the joint, reducing stress on the bond compared to rigid adhesives.
