Electrical tape 3M SCOTCH35-19X20RD Red PVC 19 mm x 20 m 600V UL Listed

3M SCOTCH35-19X20RD red PVC electrical tape is a 19 mm × 20 m roll designed for insulating, bundling and identifying electrical conductors. Rated for use up to 600 V and UL Listed, the tape combines conformability and dependable adhesion to common wire insulation materials. Its flexible PVC backing and pressure-sensitive adhesive provide a durable insulating layer for residential and light commercial electrical work.

Advantages

The tape offers reliable electrical insulation up to 600 volts and meets UL listing requirements, providing assurance of consistent performance. Its PVC backing conforms easily around irregular shapes and tight bends, while the adhesive bonds well to common cable jackets and splices. The red colour provides clear visual identification for phase marking or polarity recognition. The compact 19 mm width and 20 m length make it convenient for routine maintenance and small repair jobs.

Suitable for

• Insulating and protecting splices and wire ends in residential wiring
• Bundling and securing wire runs and cable harnesses
• Phase marking, polarity identification and colour-coding of circuits
• Minor repairs to damaged insulation on low-voltage installations
• General electrical maintenance and service tasks in homes and small commercial sites

Key specifications

• Material: PVC backing with pressure‑sensitive adhesive
• Width: 19 mm
• Length: 20 m per roll
• Rated voltage: up to 600 V
• Colour: red for identification and phase marking
• Designed for use in residential and light commercial electrical applications

How to use

Clean and dry the surface of wires or cables before application to ensure good adhesion. Start wrapping at least one tape width past the damaged area or splice, stretch slightly and overlap each turn by about half the tape width to build a continuous insulating layer. For phase marking, wrap a visible length over the existing insulation. Cut the tape cleanly at the end of the wrap and press the end firmly to secure the bond. Do not use this tape on energized equipment beyond its rated voltage or in applications requiring heat-resistant or high-performance specialty tapes.

Usage recommendations

Store the tape in a cool, dry place away from direct sunlight and heat sources. For electrical connections exposed to high temperatures, mechanical stress, or demanding industrial environments, select a tape specified for those conditions. Dispose of used tape and core according to local waste regulations.
