3M Vinyl Color Coding Tape 3/4" x 66'

Scotch Vinyl Color Coding Electrical Tape 35 is a 7 mil PVC tape with rubber resin adhesive and a dielectric strength of 1250 V/mil, so it does insulate, but it is classed as a low voltage application tape and its stated use is phase identification, color coding leads and piping, and marking safety areas. Most electricians use it for identification over a properly insulated splice rather than as the sole insulating wrap on anything above low voltage.

The rated operating range is 32 to 220 degrees F (0 to 105 C), with 105 C the maximum. That covers most conduit runs, panel interiors, and motor terminal boxes. Below freezing it is outside its rated range, so for cold outdoor work in winter warm the roll before applying.

In the 3/4 inch by 66 foot roll, Scotch 35 is offered in orange (35-ORANGE-3/4X66FT) and violet (35-VIOLET-3/4X66FT). Those two cover the high-leg and third-phase marks a lot of crews standardize on for 480Y/277 and delta systems.

The tape is abrasion and weather resistant PVC, so it is used outdoors for phase marking and for banding piping. Keep the marks within the 32 to 220 F rated range and overlap each wrap so water cannot track under the edge.

Both are premium grade vinyl tapes, but 35 is made for identification: it comes in solid colors like orange and violet for phase and system marking, piping color code, and safety area marking. It is 7 mil thick, the same build as the general purpose black vinyl tape crews use for insulating wraps. If the job is marking, use 35 in the color your spec calls for; if the job is insulating a splice, reach for the black general purpose vinyl.

It is RoHS 2011/65/EU compliant without exemption. That is the compliance statement carried on the product, useful where a facility standardizes submittals across electrical consumables.

Yes, banding piping systems is one of its stated uses, and the rubber resin adhesive sticks to conduit and painted pipe. The 19 mm band suits small diameter lines and conduit; for wide legend bands on large pipe most facilities go to a 2 inch width.

Each roll is 66 feet (20.1 m) long and 3/4 inch (19 mm) wide. A standard phase mark is a few wraps per conductor, so one roll marks a large number of leads. The 3/4 inch width is the common choice for phase taping conductors; narrower widths are used where a tighter band is wanted on small leads.
