DUROFLEX and DUROFLEX PRO - One component, thixotropic, polyurethane sealant

 

Permanently fl exible, thixotropic polyurethane sealant. DUROFLEX and DUROLFEX PRO harden by reacting with the humidity of the air. Due to them excellent adhesion and flexibility they are applicable on both horizontal and vertical surfaces.

AREAS OF USE

  • Expansion and construction joints of industrial fl oors
  • To seal prefabricated concrete structures
  • Flooring of parking lots, stores, shopping malls
  • Door and window frames
  • Construction of air-conditioning, ventilation and
  • heating systems
  • Crack sealing
  • Granite and marble surfaces
  • Dilatation joint of concrete both inside and outside

TECHNICAL FEATURES

  • Excellent adhesion on almost all surfaces (concrete,
  • wood, ceramic, marble, metal, gypsum board, glass)
  • Excellent weather resistance
  • High chemical resistance
  • Outstanding resistance to thermal fluctuations (remains
  • flexible between -40 and 80°C)
  • Great resistance to aging
  • Paintable
  • Concrete gray color (custom colors are available in case
  • of large quantities)

DIRECTION FOR USE

The application surface must be sufficiently solid and clean, free from dust, grease, moisture, or any antiadhesion matter. Clean the sides of grouts from laitance and other poorly adhering materials. MICROPRIMER is recommended to get perfect adhesion. Application of MICROPRIMER is highly recommended for joints with extreme weather exposure or in cases requiring high performance. The edges of joints should be covered by adhesive tape if necessary.

DUROFLEX and DUROLFEX PRO pastes should be applied by a press pistol or compressor. In order to provide proper fl exibility, please ensure that paste sticks only to the walls but not to the base of the gap. Apply DUROFOAM filling profile to control the depth of the gap and to avoid DUROFLEX and DUROLFEX PRO sticking to the bottom. After use the tools can be cleaned with paper towel and then acetone or xylene.
