Polyurethane Sealants

Read more

Polyurethane sealant is a high-performance adhesive and sealant that is composed of polyurethane polymers. Polyurethane has higher structural strength, excellent adhesion, and can be painted as compared to silicone or acrylic sealants and, therefore, is the choice for construction professionals and industrial applications.

Key Features of Polyurethane Sealants

  • Superior Adhesion: Bonds well to concrete, wood, metal, fiberglass, and most construction materials
  • Weather Resistance: Withstands rain, snow, and temperature extremes (-30°C to +80°C)
  • Elasticity: Maintains 25-50% joint movement capability while the seal is kept intact
  • Durability: Highly resistant to cracking, tearing, and overall degradation over time

Usage of Polyurethane Sealants

  • Sealing around doors and window frames
  • Walls and cladding expansion joints
  • Sealing around pipes penetrations in walls and floors
  • Concrete and masonry elements joint sealing
