Polyurethane Sealants

Polyurethane sealers are flexible and versatile construction sealants appropriate for a number of surfaces like wood, metal, plastic, masonry, aluminium, stucco and much more. They’re water tight and flexible under any weather condition, making them perfect for sealing gaps and joints on the exterior of structures.

Polyurethane Sealants for Construction, Glazing & Industrial Use

Polyurethane sealants are widely used for high-strength, flexible sealing and bonding across construction, glazing, marine, automotive and industrial applications. Known for their excellent adhesion, elasticity and long-term durability, PU sealants form a tough yet flexible joint that withstands vibration, movement and weather exposure.

Common Applications for Polyurethane Sealants

  • Window & door perimeter sealing
  • Expansion and movement joints
  • Roofing, cladding & metal panel sealing
  • Automotive, marine & vehicle body sealing
  • General construction and industrial bonding

Key Benefits of PU Sealants

  • High flexibility with strong adhesion
  • Absorbs vibration and joint movement
  • Excellent weather and ageing resistance
  • Overpaintable and sandable once cured
  • Suitable for metal, timber, plastics, masonry and glass

PU Sealant vs Silicone & Hybrid Sealants

Polyurethane sealants offer greater mechanical strength and abrasion resistance than standard silicones, making them ideal for joints exposed to stress and movement. Compared to hybrid sealants, PU sealants typically provide higher tensile strength and durability for demanding construction environments.
