Moisture-sealing adhesive tape for interior and exterior use



  • Protects building components against water ingress with its strong sealing effect
  • Secure bonding: butyl rubber penetrates deep into the subsurface
  • Easy to work with: very elastic - can adapt flexibly to subsurfaces and corners
  • Subsequent work can be started quickly: Sticks to stable mineral subsurfaces without primers
  • Construction in adherence with standards: for airtight bonding in accordance with DIN 4108-7, SIA 180 and RE 2020
  • Excellent values in hazardous substance testing, has been tested according to the ISO 16000 evaluation scheme

Areas of application

To seal under sills in timber structures, for joining wood-based panels to smooth mineral surfaces, to stick sub-roof panels one below the other (e.g. in grooves and transitions) and to bond these to adjoining structural elements.
