This document describes the surface preparation requirements for 3M™ VHB™ Tapes.
This technical bulletin explains how to prepare a wide range of substrates before applying 3M™ VHB™ tapes. It recommends a 50:50 isopropyl alcohol (IPA) and water mixture for most surfaces, and outlines additional steps for heavy oils, abrasion, porous materials, and unique substrates such as glass, metal and plastics.
The document also lists suggested primers and adhesion promoters, provides VOC information for cleaning agents, and describes pressure and curing requirements to achieve full bond strength. It includes a brief warranty statement and contact information for 3M Industrial Adhesives and Tapes Division.
| Cleaning solution | 50:50 IPA and water |
|---|---|
| Minimum roll‑down pressure | 15 psi (100 kPa) |
| VOC content of cleaners | >250 g/l |
| VOC of Scotch‑Grip 2262 adhesive (diluted) | 196 g/l |
A 50:50 mixture of isopropyl alcohol (IPA) and water is recommended for cleaning most surfaces before applying 3M VHB tape.
The tape should be rolled with at least 15 psi (100 kPa) pressure to develop good adhesive contact.
The cleaning solutions contain greater than 250 g/l of volatile organic compounds (VOC).
