3M 361 White Glass Cloth Tape

3M™ Glass Cloth Tape 361 is a 6.4 mil industrial grade glass cloth tape mated to a high temperature performance silicone adhesive. This product is a flame resistant tape product intended for high heat applications such as sealing high temperature ducts and chambers or usage as back up strips for submerged arc welding. Once applied for heat treatment applications this tape may be removed afterwards with little or no residue.

Strong abrasion resistant backing provides high tensile strength
Withstands temperatures from -65°F to 450°F and intermittent temperatures up to 550°F or higher, depending on the type and duration of the heat source
Silicone adhesive provides good holding power and clean removal across a wide range of temperatures

Color: White

Backing/Carrier Material: Glass Cloth

Adhesive Type: Silicone
