HYPERTECTUM DUOFLEX TX is a quick-curing, one component, thixotropic, bitumen-extended polyurethane fluid. It produces a hydrophobic, elastic membrane with very strong adhesion to most types of substrates, as well as bituminous, and excellent mechanical and chemical resistance properties. It is ideal for application on vertical surfaces: No running, no bubbling. It is based on pure elastomeric hydrophobic polyurethane resin and is extended with chemically polymerised virgin bitumen.


Waterproofing and protection of:

  • Gypsum and cement boards,
  • Asphalt membranes (for repair also),
  • Cementitious substrates,
  • Roofs,
  • Light roofing made of metal or fibrous cement,
  • Basements,
  • Foundations,
  • Cosed spaces with high humidity.

Not recommended for unsound substrates.


5 kg,

  • Economic
  • Thixotropic:Easily applied on vertical surfaces and complex shapes without running or bubbling.
  • Excellent adhesion on almost any type of surface, with or without the use of special primers.
  • Excellent thermal resistance, the product never turns soft. Max service temperature 80 oC, max shock temperature 150 C.
  • Resistance in the cold: The film remains elastic even down to -40 C.
  • Outstanding mechanical properties, high elongation, tensile and tear strength, high abrasion resistance.
  • Excellent chemical resistance.
  • Effective humidity barrier.
