3M™ VHB™ Commercial Vehicle Tapes CV62F and CV45F tapes are recommended for use in truck and trailer exterior panel bonding. 3M™ VHB ™ Tapes are fully cured adhesives. The bond strength increases as the adhesive flows onto or wets out onto the surface. This is both time and temperature dependent. These tapes have a minimum application temperature of 60°F. Below 60°F, the tape is stiffer and will form a bond slower which may result in reduced immediate handling strength.
It is coldest near the doors, so if you can do the panel bonding further back in the shop and away from the doors, that may help keep it above 60°F. Also, remember that all substrates and the tape should be above 60°F. If you store your sidewall panels or frame outside, consider bringing them in to warm up before making the bond. 3M recommends using 3M™ Primer 94 when bonding below 60°F.
