DEMCO POLYUREA /HB

Description

DEMCO POLYUREA / HB is a fast curing, 100% solid (solvent-free), aromatic, flexible, pure polyurea hybrid system that can be applied as a two-component spray on metal, concrete, wood and other recommended surfaces. It can be applied up to -30 ° C ambient temperature thanks to its gel speed. Care should be taken that the applied surface is moisture free (max. 4%). For a healthy application, it is recommended that the applied surface moisture ratio be below 5%. DEMCO POLYUREA / HB is fast curing and touch drying time is less than 30 seconds, elongation is 435% and has a flexible structure, Shore 45 – 50 D hardness. With these features, it adheres firmly to the surface, prevents its contact with the external environment, prevents water and air permeability, and is resistant to abrasion, shaking and impacts

Working Conditions

  • DEMCO POLYUREA / HB is applied in indoor and outdoor areas by providing the flexible insulation of the buildings safely.
  • Pools, water tanks
  • Treatment facilities
  • Underground buildings
  • Industrial floor pavement
  • Roof, balcony, terrace
  • Parking lots roofs
