Product description
PU Polyurethane Adhesive & Sealant – Heavy-Duty Bonding for Construction & Engineering
This high-performance one-part polyurethane adhesive and sealant is designed for strong, durable bonding and sealing across a wide range of demanding applications. With excellent resistance to water, oils, and most chemicals, it is ideal for use in construction, automotive, marine, and engineering environments where long-lasting performance is essential.
Formulated to deliver a tough yet flexible bond, this polyurethane sealant is suitable for both internal and external use, providing reliable adhesion on a variety of common building and industrial materials.
Key Uses & Compatible Surfaces
This versatile PU adhesive sealant bonds effectively to:
- Wood
- Metal
- GRP (fibreglass)
- Glass
- Rubber
- Ceramic
- Concrete and mortar
- PVC
Ideal for sealing joints, bonding components, and structural applications where strength and durability are required.
Surface Preparation
For optimal adhesion and performance:
- Ensure surfaces are clean, dry, and free from dust, grease, oil, and contaminants
- Proper preparation helps achieve maximum bond strength and longevity
How to Apply Polyurethane Sealant
- Apply using a standard sealant gun
- Cut the cartridge tip carefully without damaging the thread
- Attach the nozzle and cut at a 45° angle, slightly smaller than the joint
- Apply evenly and tool within 10 minutes using a sealant tool with a soapy solution
- Clean tools with acetone before curing; cured sealant must be removed mechanically
This ensures a smooth, professional finish and strong, consistent bond.
Limitations & Important Notes
- Not suitable for aquarium construction
- Avoid use with bitumen or asphalt
- Not recommended for joints with movement greater than 15%
- UV exposure may cause discolouration in grey and white variants
- Paintable with water-based paints; test solvent-based paints before use
