Choose heat-resistant 3M double-sided tape

It describes a temperature-related property of the specific product, not a general approval for the finished bond. For VHB variants 4611, 4646 and 4655, 3M gives separate ratings for continuous and short-term heat exposure. Whether the tape will hold in your application also depends on the substrates, surface preparation, bonding area, exposure time and load during heating. Check the product data and test the bond on the actual parts.

Continuous exposure lasts throughout service, while a short-term peak occurs only during a limited process step. A 3M data sheet specifies 150 °C continuously and 230 °C for short periods for VHB variants 4611, 4646 and 4655. Those ratings apply to the named product family and do not replace testing of the actual bond. The adhesive's load-bearing capacity decreases at higher temperatures, so both the load and its direction during heating matter.

For the 3M VHB family 4611, 4646 and 4655, the manufacturer describes bonding suitable metal parts before powder coating. Cleavage loads must be avoided during the curing cycle because adhesive strength decreases at high temperatures. Thermal expansion of the bonded parts matters too; their coefficients of expansion should be similar. Share the temperature profile and part geometry, then run preliminary tests on the actual bond.

We need the intended performance of the bond, both substrates and surfaces, the temperature profile, exposure time and load. Add the available bonding area, direction of force, required roll width or die-cut shape, and your processing steps. Krückemeyer GmbH can cut suitable tapes to size and produce die-cut parts. We assess whether the material, geometry and supplied format suit your application using the product data and your parts.
