3M 6934X66 Glass Cloth Electrical Tape

3M Glass Cloth Electrical Tape 69 is a versatile electrical tape designed for demanding applications requiring high-temperature performance and robust insulation. The tape combines a glass cloth backing with a thermosetting silicone pressure-sensitive adhesive, providing excellent mechanical strength, solvent resistance, and insulation properties. It's commonly used as coil cover, anchor, banding, and core insulation in motors, transformers, and other electrical equipment. The adhesive's elevated temperature performance ensures reliable bonding even in high-ambient temperature environments, making it suitable for Class N (392°F/200°C) temperature ratings. Its conformability, printability, and flame retardant properties further enhance its utility across a wide range of industrial applications.
