3M VHB tape is a foam tape with adhesive, which can bond a variety of materials.
3M™ VHB™ tapes are acrylic‑foam, viscoelastic tapes designed to replace rivets, spot welds, liquid adhesives and other permanent fasteners in interior and exterior bonding applications. The tapes are offered in a variety of adhesive formulations (multi‑purpose, modified, general‑purpose, low‑temperature appliable, low‑surface‑energy) and foam constructions (conformable, very conformable, firm, clear) to suit different substrate and performance requirements.
The document provides detailed product families, thickness options, performance characteristics such as 90° peel adhesion, tensile strength, static shear temperature tolerance, available roll widths and lengths, slitting tolerances, core size, shelf life, and outgassing data for aerospace use. It also includes guidance on evaluating tape suitability for specific applications and contact information for 3M converters.
| Adhesive type – Multi‑Purpose Acrylic | Bonds to metals, glass, high‑ and medium‑surface‑energy plastics and paints; resists plasticizer migration |
|---|---|
| Foam type – Conformable | High strength with ability to conform to irregularities of rigid substrates |
| 90° Peel Adhesion (typical) | Up to 22 kPa (385 lb/in²) depending on family |
| Shelf life | 24 months from date of manufacture when stored at 40 °F–100 °F (4 °C–38 °C) and 0‑95 % RH |
They have a shelf life of 24 months when kept at 40 °F–100 °F (4 °C–38 °C) and 0‑95 % relative humidity.
