Description
The 3M 7010320396 acetate cloth electrical tape 11 is a printable, tearable acetate-cloth insulation tape designed for coil wrapping, wire harness bundling, and varnish-impregnated applications. Tape 11 comes in a 72-yard roll with a 0.375" (3/8") width and an 8.0 mil nominal thickness. It uses a thermosetting rubber-resin pressure-sensitive adhesive that is designed for strong initial tack and dependable adhesion to common electrical substrates. The acetate cloth backing accepts varnishes and resins, enhancing impregnation during manufacturing processes and providing consistent dimensional performance over a service temperature range of -40 to 221°F (-40 to 105°C). This black electrical tape alternative, referred to as 3M acetate cloth tape 11 in technical data sheets, is ideal for coil insulation, transformer winding, and other applications where appearance, conformability, and temperature rating are critical to long-lasting performance.
Product Features and Benefits
High-adhesion, thermosetting rubber-resin adhesive
The 3M acetate cloth electrical tape 11 provides optimal initial tack and long-term anchorage on wires, leads, and coil surfaces, ensuring consistent mechanical and electrical performance.
Acetate cloth backing for varnish absorption
Backing readily absorbs insulating varnishes and resins, improving impregnation and bonding for coil wrapping and transformer applications.
Printable and hand-tearable for production flexibility
Printable surface supports legible identification and process marking; hand-tearable construction speeds manual bundling and dressing tasks.
Wide operating temperature range
The 3M acetate cloth tape 11 is rated for continuous use in temperatures ranging from -40 to 221°F (-40 to 105°C), which meets the temperature requirements for many electrical assemblies.
Conformable for tight-radius wrapping
Cloth construction conforms to irregular shapes and small-diameter coils without lifting or bridging, ensuring consistent insulation coverage.
RoHS compliant and manufacturing-ready
The 3M black electrical tape is RoHS 2011/65/EU compliant and suitable for die-cutting, automated wrapping, and high-volume harness production processes.
