3M Glass Cloth Electrical Tape 69 is a glass cloth electrical tape with a silicon thermosetting adhesive. The tape shall be white and 7 mils (0,177 mm) thick. The tape shall be coated on one side with pressure-sensitive adhesive which shall not require heat, moisture, or other preparation prior to or subsequent to application. The adhesive coating shall be smooth and uniform, and be free of lumps and bare spots. There shall be no separator between adjacent layers of the roll. The tape shall be UL Recognized under UL Standard 510. The tape shall perform at a temperature of 392° F (200° C) without loss of physical or electrical properties.
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.
