69 Electrical Tape - OEM
Glass Cloth With Silicone Pressure
Sensitive Adhesive
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
? 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
Typical Properties
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
