Product Description
3M Glass Cloth Electrical Tape 69 is a white, 0.178 mm electrical insulation tape with a glass-cloth backing and a non-corrosive, flame-retardant, thermosetting silicone pressure-sensitive adhesive. The adhesive applies without heat or moisture preparation, while the glass-cloth construction provides a defined tape format for high-temperature electrical assembly. The tape is designed for continuous operation not exceeding 200 deg C under its UL listing and 180 deg C under its CSA listing. Its electrical and mechanical properties suit insulation, splicing, bundling, and coil-wrapping applications where a glass-cloth tape is specified.
Key features
- High-temperature electrical insulation: The tape is rated for continuous operation up to 200 deg C under UL and 180 deg C under CSA.
- Glass-cloth silicone construction: A 0.140 mm glass-cloth backing with thermosetting silicone adhesive provides a 0.178 mm insulation tape.
- Ready pressure-sensitive application: The adhesive applies without heat or moisture preparation for coil, transformer, and motor assembly.
Applications
It is used for coil, transformer, and motor insulation, lead anchoring, high-temperature electrical splicing, and bundling.
