TEC7 is the original all-rounder.

More than 20 years after it was first launched, TEC7 still remains the most popular product for anything that needs gluing, sealing or securing. For a top-class job, tradesmen and savvy DIY enthusiasts reach for the TEC7 cartridge and rightly so!

TEC7 is the first choice for 80% of all applications.

TEC7 replaces assembly adhesive, wood glue, PU glue, silicone mastics, acrylate sealants..

Instructions

  • 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.
