General info

Why is it perfect for experts?


  • After curing, super strong and permanently elastic.
  • Free of phthalates, solvents and isocyanates.
  • Safe on mirrors, no markings on natural stone.
  • Almost odourless.
  • Even on wet, slippery surfaces.
  • Fungus and bacteria resistant.
  • Water and airtight.
  • Can be used on most building materials.

Why use Tec7 ?

  • For all applications: in the construction and sanitary sectors and general maintenance. Tec7 replaces mounting, wood and PU adhesive, silicone sealant, sanitary silicone sealant, acrylate adhesive, butyl caulking.
  • As a universal adhesive, Tec7 adheres to most substrates and does not attack synthetic materials.
  • To mirrors (vertical adhesive beads), natural stone (does not bleed through), metal, polyester, polystyrene foam, moist substrates, even under water.
  • To seal steel, welded steel and tack welded steel( also stainless steel type 316 and 316L), thus preventing rust. 
  • Overpaintable with most common paints.
  • Tec7 has lower adhesion on PP, PE, bitumen and silicones.


  • Processing temperature: from +5°C to +40°C.
  • Apply to clean, dust and grease-free substrate.
  • If necessary clean with Tec7 Cleaner or Multiclean.
  • Apply with manual or air caulking gun (best with telescopic plunger).
  • Due to the wide variety of different plastic materials and compositions, as well as materials that are prone to stress cracking, preliminary trials are recommended.
  • Test the adhesion to plastics, powder coatings, exotic woods and bituminous materials. Start by strengthening weak and/or porous substrates with Fixprimer.
  • Due to the diversity of varnishes and paints on the market we recommend preliminary tests. Using products based on alkyd resins may delay the drying process.
  • Use Tec7 Cleaner to clean and degrease safely, obtain the perfect finish, and to remove uncured Tec7 polymers. Use HP Clean to finish porous materials.
  • When glueing mirrors in sanitary facilities only apply vertical strips of adhesive to avoid stagnant moisture due to condensation.
  • Ideal adhesive thickness for optimal adhesion strength: 3 mm.
  • Tec7 has lower adhesion on PP, PE, bitumen and silicones.
