Also applied in building and HVAC industries.Tembutil-IF is a laminate of elastomeric, modified butyl rubber adhesive (improved formula for superior tack) faced with a 25 µ aluminium foil and strengthened by an extra PET foil for excellent puncture and tear resistance. A fingerlift release foil protects the adhesive side and provides easy application.Benefits Include;
- Improved Formula;
- Vapour Barrier;
- High Adhesion performance;
- M1 Fire Rating;
- Weatherproofing;
- Puncture and tear resistant.
