STK Tape supplies authentic 3M 11, 28, 1554, 1554K, and 1558 Acetate Cloth Electrical Tapes for electrical manufacturing. With flexible acetate cloth backings, excellent varnish absorption, hand-tearability, and Class A 105°C performance, they are ideal for harness bundling, transformer insulation, and electrical assembly.
3M 11 Profile: The 8.0 mil (0.203 mm) industry-standard white acetate cloth tape with a Thermosetting Rubber Adhesive, delivering aggressive initial tack and exceptional mechanical strength for heavy coil wrapping and anchoring.
3M 28 Profile: An 8.0 mil (0.203 mm) printable white acetate cloth tape featuring a Thermosetting Rubber Adhesive, formulated for wire identification, component coding, and heavy-duty coil outer wrapping.
3M 1554 Profile: A 7.5 mil (0.190 mm) high-conformability acetate cloth tape utilizing an Acrylic Pressure Sensitive Adhesive, offering high varnish resistance, optical cleanliness, and long-term age resistance without adhesive bleeding.
3M 1554K Profile: A specialized 7.5 mil (0.190 mm) black acetate cloth version with an Acrylic Pressure Sensitive Adhesive, designed for non-reflective electronic wire harness wrapping and visual concealment.
3M 1558 Profile: A 7.5 mil (0.190 mm) premium soft-weave acetate tape paired with an Acrylic Pressure Sensitive Adhesive, providing superior flexibility over complex coil margins and fine wire lead connections.
Performance Features
High Conformability & Hand Tearability: Soft woven cloth backing wraps effortlessly over irregular coil contours and tight harness junctions, tearing cleanly by hand to speed up manual production line assembly.
Excellent Varnish Absorption: The open-texture acetate cloth backing readily absorbs insulating varnishes, resins, and impregnating compounds, creating an integrated resinous bond that eliminates air voids and moisture pockets.
Dual Adhesive Options:
Thermosetting Rubber Adhesive (3M 11 & 3M 28): Cures under heat treatment to maximize solvent holding power and prevent edge flagging during varnish baking cycles.
Acrylic Pressure Sensitive Adhesive (3M 1554, 3M 1554K & 3M 1558): Provides non-corrosive, ultra-clean bonding with outstanding chemical stability and zero thermal discoloration.
Electrical Insulation Protection: Delivers a reliable Dielectric Breakdown Voltage of 2,500 Volts alongside high dielectric resistance to safeguard transformer windings and motor leads against electrical short circuits.
