3M™ RP45 VHB Tapes

Technical Help / Filters

3M™ RP45 VHB Tapes are double sided pressure sensitive adhesive (PSA) acrylic foam tapes, suitable for bonding a variety of substrates including metal, plastic, and painted materials.


The 1mm thick RP45 VHB tape takes up any surface mismatch or the effects of differential expansion. It also produces a strong waterproof bond on most surfaces. The all-acrylic construction gives 3M™ VHB RP extraordinary strength, conformability, and versatility. The composition of 3M™ VHB RP resists UV and weather damage, making it a great solution for outdoor applications.


For maximum bond strength the surfaces should be thoroughly cleaned with a 50:50 mixture of isopropyl alcohol and water. Ideal tape application is accomplished when temperature is between

21°C and 38°C and the bond can dwell for 72 hours. Initial tape application to surfaces at temperatures below 10 °C is not recommended.


The dynamic shear properties of 3M™ RP45 VHB are appropriate to stainless steel applications and static shear qualities held the following weights for 10 000 minutes during testing:

- 22 °C: 1000 g/inch²

- 70 °C: 500 g/inch²

- 93 °C: 500 g/inch²


3M™ VHB RP bonds to a wide variety of surfaces including glass, metal, some plastics, composites, and sealed wood.
