3M VHB Tape
3M™ VHB™ Tapes are high-strength bonding tapes and a proven alternative to screws, rivets, welds and other mechanical fasteners. Unlike screws or rivets – which join materials at a single point – high-strength bonding tape permanently adheres one substrate to another while spreading the stress load across the entire length of the joint. Once materials are joined with 3M™ VHB™ Tape a virtually indestructible “weld” is created.
Strength – to replace spot welds, screws, rivets and liquid adhesives
- Bond with high holding strength for static or dynamic stress
- Provide a continuous bond to distribute stress over the entire surface
- Viscoelastic properties absorb shock and flexing for reliability against wind, vibration and other stresses
- Eliminate pull-through, dimpling and weld distortion
- Damp vibration
Durability – for long term performance indoors and out
- Resists all of the following:
- High temperature
- Temperature cycling
- UV light
- Moisture and solvents
- Seal against environmental conditions
- Prevent bi-metallic corrosion
- Damp vibration to prevent metal fatigue
- Compensate for differential of thermal expansion
Meet Gene E. Uss
I’d like to introduce myself, Gene here, DuraTech’s newest employee! I’m the Information Ambassador. My job is to inform, educate, and entertain our clients. I’ll be tackling tough issues like Ooze, color matching, CSA and UL requirements, proper selection of materials and adhesives, and much more.
Have a question? Email it to me at firstname.lastname@example.org. If you submit your photo and a brief description of some of your key characteristics (witty, dislikes cats, likes Hawaiian shirts, etc.), you may find yourself making a guest appearance in one of my strips!
Look for me on Facebook at Facebook.com/DuraTech.

Proper Application Surface Preparation
We not only want you to be happy with the quality of our product, we also want to help you be successful in your application of our product. The following are general recommendations that should be taken to apply self-adhesive products. The surface applied to should be as smooth as possible. 50-60 PSI should be applied with a 1- 2 second dwell. Application at room temperature will achieve ultimate bonding strength within 72 hours. Application at 120-150° F will achieve ultimate bonding strength within 24 hours. Specific information on preparation and application is listed below.
For best results the application surface and surrounding ambient atmosphere should be 50° F or above.
Many of the following solvents are either flammable or toxic or both and manufacturer’s recommended precautions should be followed.
Mild Cleaners: Standard commercial detergent solutions, mild soap, or warm water.
Solvents: Low boiling hydrocarbons, e.g. Shell X20, X55, X60 or equivalent; Heptane, toluol or xylol, and keytones (acetone, M.E.K.). Care should be taken to ensure plastic or rubber surfaces are not detrimentally affected by contact with the solvent. Use personal protection equipment recommended on MSDS when handling solvents.
