Benefits/Advantages To Customer

Fast assembly time: 3MVHBTapes apply quickly and easily and provide immediate handling strength to allow continued processing. VHB tapes eliminate refinishing work after spot welding and cure delay time required for liquid adhesives.

Improved appearance: VHB tapes allow cabinet doors and walls to have a smooth finish. VHB tapes eliminate surface defects caused by spot welding and eliminate the ooze and mess of liquid adhesives.

Versatile: VHB tapes offer a wide selection of adhesive systems that allow bonding of the stiffener either before or after the painting process. 3MVHBTape 4611 bonds to bare metal and holds parts together during the washes and high temperature bake of a powder paint cycle. 3MVHBTape 5952 bonds to most liquid and powder painted surfaces without the need to prime or abrade the surface first.

Durable: VHB tapes provide strong adhesion and durable bonds that withstand vibration, impact and outdoor weathering conditions.

UL listing: Many VHB tapes (including 3MVHBTapes 4611 and 5952) are listed under UL 746C.

3MVHBTapes can be applied to the back side of the hat channel either by hand or by using automatic equipment. The liner is removed and the hat channel stiffener is pressed into place on the clean painted metal surface of the enclosure wall or door. A simple nip roller can be used to apply the appropriate pressure required to ensure good adhesive contact over the entire stiffener.
