with Silicone Pressure-Sensitive Adhesive
Data Sheet
Description
November 2008
3M ? Glass Cloth Electrical Tape 68 is a 7-mil woven insulating glass cloth tape with a
silicone pressure-sensitive adhesive. This tape is used to electrically insulate and
provide mechanical protection at temperatures to 356° F (180° C). This tape provides
insulation protection for use as coil cover, anchor, banding and core, layer and
crossover insulation. This tape features a non-corrosive adhesive. It is conformable,
printable and flame retardant.
