3M 69 Temp Glass Cloth Tape (3/4″ X 66′)

3M™ Glass Cloth Electrical Tape 69 is a white glass cloth tape with a high temperature thermosetting silicone pressure-sensitive adhesive. It is designed for use in 600-volt dry location applications motors, and transformers with and without varnish coating. Key attributes like high mechanical strength and resistance to high temperatures provide excellent performance. The thermosetting adhesive provides an increased bond once applied in areas of high ambient temperatures. The thermosetting adhesive provides elevated temperature performance up to Class N 392°F (200° C) temperature rating.

This tape provides insulation and solvent-resistant protection for use as coil cover, anchor, banding and core, layer and crossover insulation. This tape features a noncorrosive adhesive. It is conformable, printable and flame retardant.

Applications

• Insulating electric and induction-type furnace power supply leads
• Securing high-temperature, non-PSA insulation (such as asbestos and glass) in high-temperature areas
• Securing Scotch® Fire Retardant Electric Arc Proofing Tape 77
• Splicing wire SF and SFF rated 302° F (150° C), 356° F (180° C)
• Reinsulating and repairing coils on mining machines
• Splicing silicone-covered glass wire where splices require more abrasion resistance and mechanical strength than can be provided by silicone tapes Insulating Class “H” dry-type transformer leads
• Insulating splices made on SA type wire in heat treat areas
• Especially suited to high-temperature applications
• Used in a variety of coil/transformer and motor applications, including an outer wrap for bobbin wound coils, banding arbor wound coils, lead pad hold down, end turn and lead anchor and connection.
