What are the benefits of MasterSeal M 820?

  • Application to vertical surface without runs – installation to walls not problem
  • Monolithic – no laps, welds or seams
  • Fully bonded – moves with the structure
  • High water vapour permeability – low risk of blistering in service
  • Crack bridging capability – can cope with cracks that occur after installation
  • Solvent and monomeric isocyanate free – increased safety for applicators
  • Unaffected by standing water or ground water – suitable for constant water contact
  • Thermoset – does not soften at elevated temperatures encountered on a roof
  • Remains elastic at low temperatures-Tg approx. -45°C – suitable for all Asia Pacific climates
