Scotch ® Mastic Tape and Electrical Moisture Sealent beside each other

Mastic sealant

Mastic compounds typically come in different shapes and sizes to make wrapping odd shapes easy. Like rubber tapes, they are overwrapped with vinyl tape for abrasion resistance.

Expert tip
Avoid applying excessive amounts of mastic to prevent oozing.

Electrical tape is an essential component of any installation, repair and manufacturing project. 3M invented vinyl electrical tape and today we offer a wide variety of durable, reliable electrical tapes, each designed with one or more applications in mind; insulating, protecting, sealing and/or marking.
