3M ET6919X33 Glass Cloth Electrical Tape, 19 mm x 33 m, White, 12-Pack

The 3M ET6919X33 Glass Cloth Electrical Tape is a high-performance insulation solution engineered for environments where heat resistance and mechanical strength are critical. This white tape is constructed from a durable glass cloth backing coated with a specialized silicone adhesive, ensuring reliable performance in demanding electrical applications. Each roll provides a width of 19 mm and a length of 33 m, with a total thickness of 0.18 mm, making it suitable for precise wrapping and bundling tasks.

Advantages

The primary benefit of this glass cloth tape is its exceptional thermal stability, which allows it to maintain its integrity in high-temperature conditions where standard tapes might fail. The silicone adhesive provides excellent adhesion to various surfaces and offers long-term durability. Furthermore, the glass cloth backing provides superior mechanical protection against abrasion and puncture, ensuring that electrical components remain securely insulated and protected during operation.

Suitable for

• Insulating electrical connections in high-temperature environments
• Bundling wires and cables that require heat resistance
• Wrapping coils and transformers
• General electrical maintenance where mechanical strength is required

When it may not be suitable

This tape is not intended for low-temperature applications where the silicone adhesive may not achieve optimal bonding. It is also not recommended for use in environments where high moisture resistance is the primary requirement, as glass cloth tapes are generally designed for thermal rather than moisture-sealing purposes.

Key specifications

• Material: Glass cloth backing with silicone adhesive
• Breakdown voltage: 600 V
• Width: 19 mm
• Length: 33 m
• Thickness: 0.18 mm
• Color: White
• Quantity: 12 rolls per pack

How to use

To apply the tape, ensure the surface is clean, dry, and free from oils or contaminants. Unroll the required length of tape and apply it with firm, even pressure to ensure proper contact between the adhesive and the substrate. For electrical insulation, overlap the tape by approximately 50% on each wrap to create a consistent and secure layer. When finishing the application, press the end of the tape firmly to prevent lifting.

What to consider before purchase

• Verify the temperature requirements of your specific application
• Ensure the 19 mm width is sufficient for your cable or component size
• Confirm that the 600 V breakdown voltage rating meets your electrical safety standards

Usage recommendations

For optimal performance, store the tape in a cool, dry place away from direct sunlight. When applying to complex shapes, maintain consistent tension to avoid wrinkles and ensure a uniform insulation layer.
