3M™ VHB™ Tapes are made with acrylic foam which is viscoelastic in nature. This gives the foam energy absorbing and stress relaxing properties which provides these tapes with their unique characteristics. The acrylic chemistry provides outstanding durability performance.
The document provides an overview of 3M™ VHB™ tapes, acrylic‑foam adhesive tapes designed to replace rivets, spot welds and liquid adhesives in interior and exterior bonding applications. It describes the various adhesive chemistries (multi‑purpose, modified, general‑purpose, low‑temperature appliable and low‑surface‑energy) and foam constructions (conformable, very conformable, Finm, clear) that give each product family its unique performance.
Detailed tables list product families, tape thicknesses, colors, release liner types, mechanical properties such as 90° peel adhesion, tensile strength, dynamic shear, static shear temperature tolerance, available roll widths and lengths, shelf life, and outgassing characteristics. The data are presented as typical values for engineering reference.
| Adhesive Type | Multi‑Purpose Acrylic |
|---|---|
| Foam Type | Conformable |
| Shelf life | 24 months |
The tapes have a shelf life of 24 months when stored at 40 °F–100 °F (4 °C–38 °C) and 0‑95 % relative humidity.
