Seal-it® 380 FOIL-BOND

Seal-it® 380 FOIL BOND is a high-quality, professional assembly adhesive, based on Hybrid technology, that is specifically intended for bonding plastic films and vapour control layers. The adhesive cures through humidity to a durable, self-adhesive rubber.



  • Specially developed for bonding plastic films (PE, PVC, EPDM, DPC) to stone, concrete, plaster, metal and wood.
  • For bonding and waterproof and airtight finishing of synthetic films.
  • Suitable for bonding the most common membranes and vapour barriers.
  • Bonding of PP foils around wood and carpentry, e.g. window frames.


  • Durable, permanent plasto-elastic.
  • Excellent adhesion without primer on practically all surfaces, even when moist.
  • Superb processing properties, professional A quality.
  • Free of plasticisers, phthalates, isocyanate, solvents and silicone.
  • Very low emission: certified VOC emission class A+.

Application conditions

  • Apply the material vertically (ventilated) in beads spaced between a minimum of 10 cm and a maximum of 20 cm apart. Do not apply in dabs!
  • Application temperature (ambient and surface) between +5 °C and +40 °C.
  • On clean, uncontaminated, compatible, stable, grease-free and dust-free surfaces.
  • Degrease the surface properly using Seal-it® 510 CLEANER.
  • Seal-it® 380 FOIL BOND has a broad bonding spectrum, but highly porous surfaces should be pre-treated with Seal-it® 520 PRIMER and non-porous surfaces with minimal bonding should be treated with Seal-it® 525 Clean & Bond.
