Professional-grade 7-mil glass cloth electrical tape with silicone adhesive, UL/CSA rated for high-temperature insulation up to 600V, ideal for transformers, motors, and coil wrapping applications.
3M™ Glass Cloth Electrical Tape 69 is a professional-grade white electrical tape measuring 0.178 mm (7-mil) thick, featuring a 0.140 mm (5.5-mil) glass cloth backing coated with a non-corrosive, high-temperature, flame retardant thermosetting silicone pressure-sensitive adhesive. This premium tape is specifically designed for industrial and occupational applications requiring reliable electrical insulation and superior temperature performance. The tape is UL recognized and rated for 200°C (392°F) and CSA certified for 180°C (356°F), making it suitable for demanding electrical applications up to 600 volts in dry locations. It is commonly used in coil and transformer applications, motor insulation, bobbin wound coil wrapping, arbor wound coil banding, lead pad hold-down, end turn protection, and lead anchor connections.
This glass cloth electrical tape combines exceptional durability with printable surface capabilities, allowing for easy identification and marking in complex electrical assemblies. The pressure-sensitive silicone adhesive provides excellent adhesion to various substrates while maintaining its properties across the full temperature range. The tape features a dielectric strength of 3000V and insulation resistance of 4.8 x 10^4 megohms, ensuring reliable performance in critical electrical applications. With RoHS 2011/65/EU compliance and QPL listing (QPL-19166 per MIL-I-19166), this tape meets stringent military and industrial standards. The product offers a 5-year shelf life when stored according to 3M recommended conditions, and each case contains 72 rolls for bulk industrial use.
Designed exclusively for trained industrial and occupational professionals, this tape is not intended for consumer use. The 36-yard length per roll (32.9 meters) provides substantial coverage for large-scale electrical projects, while the 0.5-inch (12.7 mm) width makes it versatile for various winding and wrapping applications. Whether you're working on transformer coils, motor windings, or high-voltage electrical connections, 3M Glass Cloth Electrical Tape 69 delivers the reliability and performance that industrial professionals demand.
