One-component PU Sealant, polyurethane adhesives 




Is a high performance fast cure one component polyurethane sealant. When cured it will form a tough, flexible seal capable of cyclic expansion and compression movement. Joint or fabrications formed with this sealant can be expected to extend and compress a total of 50%(±25%) of the original joint dimensions


Is virtually unaffected by normal weathering conditions such as rain, sunlight, snow, sleet, ozone, atmospheric contamination and pollution, it’s excellent weather ability it to retain it’s original properties after years of exposure, its physical properties remain relatively unchanged over a wide temperature range(-40°c to 70°c)


Recommended uses:


  1. For sealing floor joints
  2. Granite, sandstone and marble pointing
  3. GRC, Fiberglass & Specialty panel system
  4. Trafficable – Plats, stairs, road, runways, aprons and pavements
  5. Vertical – Precast, Blockwork, aluminum, plasterboard, timber and most common building substrates
  6. Pick resistant – Prisons, cells, schools and public amenities
  7. Chemical resistant – service stations, hangers, aprons and bunded areas
  8. Metal curtain wall facades
  9. Potable water tanks
  10. Sealing construction and expansion joints
