Pressure Sensitive Adhesives for Tapes and Self-adhered Membranes in Building
Roofing Underlayment Membranes
Roofing underlays must be wind‑tight, rain‑resistant, and diffusion‑open, with seams that survive UV, heat, wind load, and construction handling.
HM PSAs offer:
- Secure overlap bonding on PP/PE facers, wood‑fiber boards, OSB, and mineral substrates.
- Moisture‑safe performance that supports breathable (diffusion‑open) designs.
- Heat resistance up to ~85 °C for rooftop environments.
- Elastic, durable bonds that handle movement, pressure pulses, and temperature cycling.

TPO & EPDM Self-adhered roofing membrane
Self-adhered TPO and EPDM membranes depend on robust adhesive performance to ensure watertightness, durability and quick installation.
UV PSAs and MC PSA offer
- Immediate bond, zero cure time → fast, clean installs.
- High peel and shear on films and insulation facers (e.g., foil/film‑faced PIR/PUR; PP/PE fleeces).
- Water hold‑out & ageing resistance → supports long‑term watertightness.
- Thermal stability & UV durability → for exposed edges and staged installs.
- Low‑odor, solvent‑free options → better jobsite experience and ESG alignment.
How PSA technologies address challenges in building tape and self-adhered membrane applications
Designed for end-use tape applications in the building and construction market, acrylic pressure sensitive adhesives (waterborne, UV and solvent based), hot melt PSA and moisture cure PSA help ensure your construction materials offer high-performance even when application requirements evolve.
More sustainable building with higher performance
Across Europe and North America, manufacturers are shifting from bitumen to butyl and acrylic PSAs to meet sustainability targets and achieve higher performance.
Modern tapes and self-adhered membranes require adhesives that provide strong, long‑lasting adhesion on OSB, plywood, engineered wood, concrete and advanced membrane facers, while remaining environmentally responsible.
PSA technologies are designed for these modern building needs. They deliver:
- High adhesion on multiples substrates but more specifically wood substrates supporting Europe’s growth in timber wood construction
- Strong tack enables fast installation
- Good ageing resistance
Bostik developed PSA solutions to fit latest requests of building & construction industry: high breathability, fire retardancy, high shear and water resistance. We also offer acrylic PSAs solvent free and low VOC formulations. For tapes and self-adhered membrane manufacturers, this means more reliable bonding, higher durability, and products that meet rising environmental expectations without compromising installation efficiency.
Polyvalent Seaming Tapes with Wide Application
Building components manufacturers increasingly need seaming tapes that perform year-round, bond to multiple substrates and work on both interior and exterior layers.
PSAs technologies can provide:
- Immediate adhesion on multi-substrates: plywood, OSB, membranes, metal, and wood‑fiber boards
- Cold‑weather bonding down to –20 °C for winter installation
- Good temperature, ageing and humidity resistance
Meeting New Safety Regulations for Facade Systems
Following regulations updates such as EN 13501-1, adhesives used in facade systems must offer reliable adhesion while supporting fire retardant performance requirements.
The challenge is to maintain strong adhesion and ageing resistance without compromising safety.
PSA solutions can offer:
- Reliable adhesion across various substrates (ex, woven glass fiber)
- Good ageing properties
- Formulation complying with fire retardancy regulation (ex: EN 13501-1)
