3M™ 9469 Adhesive Transfer Tape

3M™ 9469 Adhesive Transfer Tape is a very firm acrylic pressure-sensitive system. It features very high shear holding power. Bond strength increases substantially with natural ageing and is also dependent upon the amount of adhesive-to-surface contact developed. Firm application pressure develops better adhesive contact and thus improves bond strength.

 

To obtain optimum adhesion, the bonding surfaces must be clean, dry, and well-unified. Typical surface cleaning solvents are isopropyl alcohol & water mixture (rubbing alcohol) or heptane. In some cases, bond strength can be increased, and ultimate bond strength can be achieved more quickly by exposure of the bond to elevated temperatures (e.g. 65°C) for one hour. This provides better adhesive wet-out on to the substrates.

 

It may be necessary to seal or prime some substrates prior to bonding. Most porous or fibred materials (e.g. wood) will require sealing to provide a unified surface. Some materials (e.g. copper, brass, plasticised vinyl) will require priming or coating to prevent interaction between the adhesive and substrates.

 

The ideal tape application temperature range is 21°C to 38°C. Initial tape application to surfaces at temperatures below 10°C is not recommended, because the adhesive becomes too firm to adhere readily. However, once properly applied, low temperature holding is generally satisfactory.

VHB™ joining systems are suited for use in many interior and exterior industrial applications. In many situations, they can replace rivets, spot welds, liquid adhesives, and other permanent fasteners.

 

Each product in the VHB family has specific strengths. These can include high tensile, shear and peel adhesion and resistance to solvents, moisture, and plasticiser migration. All VHB™ tapes should be thoroughly evaluated by the user under actual use conditions with intended substrates, especially if expected use involved extreme environmental conditions.
