    A HIGH ELASTIC, ULTRA-FAST CURING, SPRAY APPLIED 100% POLYUREA MEMBRANE FOR USE IN WATERPROOFING APPLICATIONS

    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 hot spray equipment.

    FIELDS OF APPLICATION

    MasterSeal M 689 is used in a variety of waterproofing applications, especially where a high degree of chemical and mechanical resistance is required.
    This includes:
    • Waste water treatment plants (urban and industrial), both in the inflow and outflow areas.

    • Sewage effluent pipelines.

    • Steel and concrete pipes.

    • Secondary containment bunds in chemical and petrochemical industries.


    Additionally, MasterSeal M 689 can be applied on:
    • Flat and architectural roofs.

    • Horizontal and vertical substrates.

    • Internal and external areas.

    • Concrete, cementitious mortar or steel substrates.
