HYPERTECTUM DUOFLEX is a fast-curing, twocomponent, 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. It is based on a pure elastomeric hydrophobic polyurethane resin extended with chemically polymerised virgin bitumen.

  • CE: ETA-10/0095,
  • ASTM C836-95,
  • Root resistance,
  • Compliance / performance.

Waterproofing and protection of:

  • Gypsum and cement boards,
  • Polyurethane insulation foams,
  • Asphalt membranes,
  • EPDM membranes,
  • Bathrooms (under tiles),
  • Verandas and balconies (under tiles),
  • Flower pots and roof-top gardens,
  • Light roofing made of metal or fibrous cement,
  • Non-potable water tanks,
  • Basements,
  • Foundations,

20+20 Lt


Not recommended for unsound substrates.

  • Components easily mixed, 1:1 by volume.
  • Fast curing.
  • Thick, bubble-free, membrane possible.
  • Being a two-component product means that the quantities not mixed can be stored for later use.
  • Its low modulus gives it excellent substrate crack-bridging properties.
  • Excellent adhesion on almost any surface, with or without the use of special primers.
  • No thinning is required but pure xylene may be used.
  • Excellent thermal resistance, the product never turns soft. Max service temperature 80 oC, max shock temperature 200 C.
  • Resistance in the cold: The film remains elastic even down to -40 C.
  • Excellent mechanical properties, high elongation, tensile and tear strength, high abrasion resistance.
  • Good chemical resistance.
  • Good water vapor barrier properties.
  • Can also be used as a joint sealant.
