Data Sheet

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
