BASF - MasterSeal M 689
Application

Used in a variety of waterproofing applications where a degree of chemical resistance is required. These include sewage effluent, and secondary containment bunds within the dirty water, chemical and petrochemical industries. Can be applied to the majority of substrates irrespective of falls. Spray delivered and ultra-fast cure enables easy application to form a monolithic waterproofing membrane on simple and complex surfaces.

Description

MasterSeal M 689 is a solvent free, two component waterproofing membrane. It is highly reactive and can only be applied by special two component spray equipment.

Features and benefits:

  • Application to vertical surfaces without runs.
  • Easy application to complicated details.
  • Can be applied to a wide range of substrates with the appropriate primer.
  • Monolithic – no welds (no hot work or torches) or seams.
  • High water vapour permeability – low risk of blistering.
  • Excellent mechanical, chemical and crack bridging properties.
  • Resistant to standing water.
  • Thermoset – does not soften at high temperatures and remains elastic at low temperatures; Tg: 45°C (approximately).
  • No solvent.
  • CE marked.
