3M™ RP25 VHB Tapes

Technical Help / Filters

 

3M™ RP25 VHB tapes produce a strong waterproof bond on most surfaces. The all acrylic construction gives this tape extraordinary strength, conformability, and versatility. The composition of VHB tape resists UV and weather damage, making it a great solution for outdoor applications. It also offers high solvent resistance and dynamic shear properties on stainless steel. 

 

3M™ VHB bonds to a wide variety of surfaces, including glass, metal, some plastics, composites, and sealed wood. It’s tensile strength on stainless steel is 550 kPa, and temperature performance on stainless steel is 121°C when dwelled for 4 hours at elevated temperature with 100 g weight, whereas long terms (days and weeks) is 93 °C.

 

For maximum bond strength, surfaces should be thoroughly cleaned and prepared 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 approximately 72 hours. Initial tape application to surfaces at temperatures below 10 °C is not recommended.

 

This multi-purpose acrylic comprises of a closed-cell, conformable acrylic foam with a density of 720 kg/m3, and is 1.57mm thick, making it suitable for irregular surface applications where precision is required.
