3M™ Glass Cloth Electrical Tape 69
3M™ Glass Cloth Electrical Tape 69 is a white, 7-mil (0.178 mm) tape with a 5.5-mil (0.140 mm) glass cloth backing coated on one side with a non-corrosive, high-temperature, flame-retardant, thermosetting silicone pressure-sensitive adhesive. The adhesive requires no heat, moisture, or other preparation for application. It's designed for UL applications rated up to 600 volts in dry locations and is commonly used in coil, transformer, and motor applications.
Applications include: Outer wrap for bobbin-wound coils, banding for arbor-wound coils, lead pad hold-down, end turns, lead anchor and connections
