3M 69 Glass Cloth Electrical Tape

3M™ Glass Cloth Electrical Tape 69 is an industrial grade 7 mil electrical tape constructed with a white glass cloth backing mated to a high temperature thermosetting silicone adhesive. This product is suitable for continuous high heat electrical insulating applications. Constructed for durability and effectiveness in high temperature applications, this product provides increased bond when applied in high temperatures and increased abrasion resistance and mechanical strength compared to tapes with silicone backings.

Thermosetting adhesive provides an increased bond once applied in areas of high ambient temperatures
Edge-tear resistant, conformable, high-temperature, flame resistant
UL recognized for continuous use up to 200°C/392°F

Color: White

Backing/Carrier Material: Glass Cloth

Adhesive Type: Thermosetting Silicone
