1. Product Description
3M™ 69 Glass Cloth Electrical Tape is a white glass cloth
tape with a high-temperature thermosetting silicone adhesive.
The thermosetting adhesive provides an increased bond once
applied in areas of high ambient temperatures. 69 Tape is UL
recognized for continuous use up to 200°C. It conforms to
Military Specification No. MIL-I-19166C.
2. Applications
• Insulating electric and induction type furnace power
supply leads
• Securing high temperature, non-PSA insulations (such as
asbestos and glass) in high temperature areas
• Securing Scotch 77 Fire Retardant Electric Arc Proofing
Tape
• Replacing 3M 27 Glass Cloth Electrical Tape in locations
where a higher-temperature tape is needed
• Reinsulating and repairing coils on mining machines
• Reinforcing insulation in electrical installations where
heavy loads cause high heat and breakdown of original
insulation (e.g. motor control exciter feeds)

• 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
