  • Processing temperature from +5°C to +40°C.
  • Apply to dry, 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).
  • Test the adhesion to plastics, powder coatings, exotic woods and bituminous materials. Start by strengthening weak and/or porous substrates with Fixprimer.
  • Not paintable!
  • Alkyd resin will harden slowly.
  • 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.
