3M™ Glass Cloth Electrical Tape 69 is a premium-grade, high-performance woven glass cloth tape engineered for superior electrical insulation and mechanical strength. Coated with a high-temperature, pressure-sensitive thermosetting silicone adhesive on one side, this tape offers exceptional flame resistance, edge-tear resistance, and an ability to perform reliably under high thermal loads.

Designed to perform reliably in extreme environments, this 7.0-mil thick tape is perfect for insulating motor leads, protecting high-voltage components, and providing high-heat crossover insulation in demanding industrial applications. It meets the rigorous quality and safety standards of military specification MIL-I-19166C.

Key Features & Benefits

• Thermosetting Silicone Adhesive: Formulated to offer non-corrosive, solvent-resistant protection with increased bonding stability under high thermal loads.
• High Mechanical Performance: Woven glass cloth backing provides robust edge-tear resistance, high tensile strength, and minimizes shrinking or rotting.
• Premium Insulation: Engineered for 600V dry-location applications, making it ideal for motors, transformers, and coil wrapping.
• Printable Surface: Backing allows for easy marking and identification during complex wiring assemblies.
