Smart adhesives for roofing membranes and underlays 

Bostik’s underlay overlapping, self-adhesive membrane and membrane lamination adhesives, based on hot melt pressure sensitive (HMPSA), hot melt polyolefin (HMPO) and hot melt polyurethane (HMPUR) technologies, offer distinct advantages for over other technologies that make it easy to address key application needs.

When using an HMPSA for underlay overlapping and self-adhere roofing membrane applications, you can:

  • Increase installation ease of use with integrated self-adhesive stripe for overlapping bonding 
  • Enhance performance, insulation capabilities and efficiencies due to excellent initial adhesion with high tack

When using an HMPO for membrane lamination applications, you can:

  • Increase process flexibility and layering abilities due compatibility with a wide range of substrates and application systems  
  • Improve productivity and ease of use due to no curing phase 

When using an HMPUR for membrane lamination applications, you can:

  • Increase ageing performance and building protection with elevated service temperature, UV and humidity resistance  
  • Enhance energy efficiency and improve worker safety with low application temperature
