HYPERDESMO-PB-2K Two-component polyurethane membrane for waterproofing & protection

Description :

HYPERDESMO-PB-2K is a fast-curing, two- component, bitumen-extended polyurethane fluid. It produces a highly elastic membrane with strong adhesion to many types of surfaces and excellent mechanical and chemical resistance properties.

Usage :

  • non-potable water tanks
  • light roofing made of metal or fibrous cement
  • flower pots and roof-top gardens
  • verandas and balconies (under tiles)
  • bathrooms (under tiles)
  • Waterproofing and protection of Gypsum and cement boards, polyurethane insulation foams, asphalt membranes
  • basements
  • foundations
  • bridge platforms

Features and benefits :

  • Good chemical resistance
  • Excellent mechanical properties, high elongation, tensile and tear strength, high abrasion resistance
  • Resistance in the cold
  • No thinning is required but SOLVENT-01 may be used
  • Excellent adhesion on almost any surface, with or without the use of special primers
  • Its low modulus gives it excellent substrate crack-bridging properties
  • Being a two-component product means that the quantities not mixed can be stored for later use
  • Thick, bubble-free, membrane possible
  • Fast curing
  • Components easily mixed, 1:1 by volume
  • Good water vapor barrier properties

How to use :

Clean the surface using a high pressure washer, if possible. Remove oil, grease and wax contaminants. Cement laitance, loose particles, mould release agents, cured membranes, etc. must be removed
Priming:
Choose primer from the Primer Selection Table and follow the application instructions given on its prospectus
Mixing:
Mix   equal   volumes   of   the   two  components manually or with a low speed (300 rpm) mixer. Apply mixed quantities immediately
For application by airless spraying,   the mix may have to be thinned with a small quantity of SOLVENT-01, especially for low-power applicators.
