3M 4646 Double-Sided Foam Tape

This 3M 4646 double-sided foam tape comes in a continuous roll measuring 1 in wide by 5 yd long with a 1/32 in thickness. The dark gray polyethylene foam carries adhesive on both sides and includes a liner. It is suited for assembly, manufacturing, automotive, aviation, construction, electronics, general maintenance, metalworking and warehouse tasks, working on surfaces such as ABS, acrylic, glass, metal, nylon and polycarbonate both indoors and outdoors.

Temperature performance range

The tape operates continuously from -31 Degrees F up to 194 Degrees F, so it remains functional in cold storage areas and in engine-bay or electronics-enclosure heat. This wide range means the bond does not become brittle in freezing conditions or soften excessively during sustained high-temperature exposure typical of industrial or automotive environments.

Indoor and outdoor durability

The polyethylene foam core resists moisture and environmental cycling, allowing the tape to maintain adhesion in normal indoor and outdoor use without rapid degradation. Its construction provides a consistent bond line on the listed compatible substrates, and the included liner protects the adhesive until application.
