Flex PU

Single-component polyurethane liquid membrane for waterproofing and protection. Suitable for waterproofing and protection of roofs, lightweight sheet metal or fibre cement roofs, asphalt membranes, parking lots and stadium stands, bridge platforms and irrigation channels.
  • Excellent adhesion to almost any surface, with or without special adhesion promoters.
  • No dilution is necessary.
  • Excellent weathering and UV resistance.
  • Excellent thermal resistance.
  • Resistance to low temperature: the membrane remains elastic even at -40 °C.
  • Excellent mechanical properties, high tensile strength and tear resistance, abrasion resistance.
  • Good resistance to chemical agents.

Flex PU is a single-component, low-viscosity liquid polyurethane that vulcanizes with atmospheric humidity. It produces a resistant and elastic membrane with excellent adhesion to different surfaces. It contains a small percentage of solvent (xylol) and does not require further dilution. Apply with roller, brush or airless in two layers with a minimum total consumption of 1.5 – 1.8 kg/m2. The product is based on pure polyurethane, elastomeric and hydrophobic resins, with the addition of special inorganic fillers that provide the material with excellent resistance to weather, chemical agents, UV rays, mechanical and thermal stress. The product is recommended for use on visible areas; available in white, red and light grey. The product complies with the EU guidelines for these types of materials, ΕΟΤΑ (European Organization of Technical Approval).
