3M™ VHB™ Tapes series of products have excellent durability and can meet the needs of various harsh environments.
The bulletin reviews the chemical composition of 3M VHB™ acrylic foam and adhesive transfer tapes and presents test results for moisture resistance, UL durability, accelerated and outdoor weathering, thermal cycling, and fatigue resistance. Test data include temperature exposure, UV aging, and solvent resistance, showing high strength retention over years of service.
Application examples illustrate the use of VHB™ tapes on ambulance bodies, curtain‑wall facades, semi‑truck panels, and aircraft wing flaps, highlighting their ability to withstand harsh temperature extremes, humidity, UV exposure, and mechanical fatigue.
| Peel adhesion retention after 5 years at 150°F (65°C) | 92 % |
|---|---|
| Maximum temperature rating (UL 746C) for VHB Foam Tape on metal substrates | 110 °C |
VHB tapes are listed under UL 746C, which requires high‑strength retention after extended exposure to temperature, humidity, cold, and cyclic conditions.
