Application

  • Universally applicable adhesive and sealant.
  • All applications in construction, sanitary and general maintenance.
  • Tec7 adheres to most surfaces and does not attack plastics.
  • Safe to use on all materials, mirrors, natural stone, polystyrene, non-ferrous metals, most plastics, ...
  • Can be used on damp surfaces, even submerged in water.
  • Can be quickly painted over with most common paints (do not use with alkyd paints).
  • Tec7 has less adhesion to PP, PE, PTFE, bitumen and silicone. Adhesion on PP is improved with the PT7 primer.

Technical information

Specifications

Instructions

  • Processing temperature between -10°C and +40°C. At temperatures below 0°C, curing will be considerably slower.
  • Apply to a clean, stable, dust- and grease-free surface.
  • Use Tec7 Prepare & Finish for safe cleaning and a perfect finish.  In case of heavy soiling, clean using Tec7 Cleaner and/or Multiclean.
  • Test adhesion on plastics, powder coatings, exotic woods and bituminous materials.
  • Strengthen weak and/or porous substrates first with Poxy Primer. 
  • PT7 primer ensures optimum adhesion on difficult (LSE) plastics and powder coating.
  • Tec7 hardens through a reaction with (air) moisture.  Use Tec7 in lines, not in thick dots. Dots will take longer to harden. When used between two airtight materials, it is recommended to dampen one of the surfaces very slightly.
  • Use vertical adhesive strips to avoid moisture and dust accumulation.
  • Ideal adhesive thickness: 0.5 mm to 3 mm.  Thin layers = higher strength.  Thicker layers = higher elasticity. 
  • Can be painted over after skin formation.  Do not use with alkyd-based lacquers and paints.
  • Use Tec7 Cleaner and/or Tec7 Powerwipes to clean tools and/or remove uncured Tec7. Clean hands and skin with Tec7 Powerwipes.
  • Cured Tec7 can only be removed by mechanical means.  Any residue can be removed with Remove All if the substrate can withstand it.
