Intertape 4618 Glass Cloth Tape
Intertape 4618 is a glass cloth-backed tape with heat-resistant silicone adhesive for high-temperature applications. This tape resists edge fraying and rotting and is flexible and varnish-absorbent. It's used in applications requiring solvent, flame, and abrasion resistance, including high-temperature coil insulation wrap, harness wrapping, and splicing. It's ideal for motor repair shops for bundling and banding heavy-gauge magnet wire and for slot cell edge taping. 4618 meets MIL-I-19166C government compliance.
Applications include: High temperature coil insulation wrap, harness wrapping, splicing, motor repair shops bundling and banding heavy gauge magnet wire, slot cell edge taping, dry-type and oil-filled transformers, electrical/electronic, EV battery, generators, harness cable assembly, military/government certified, motors, MRO, power supplies and instrumentation, relays, solenoids and magnetic coils, solar and alternative power, UL-approved 200°C
