3M™ Acetate Cloth Electrical Tape 11 features a conformable black woven cellulose acetate cloth backing paired with a thermosetting rubber adhesive. Its porous weave absorbs electrical insulating resins and varnishes completely, locking coils into a solid, moisture-resistant matrix. Highly conformable and easily torn by hand for rapid coil bundling.
Key Performance Highlights
- Conformable black woven acetate cloth backing absorbs electrical varnishes and resins readily
- Aggressive thermosetting rubber adhesive cures under baking to form permanent bond
- Non-corrosive formulation prevents copper wire pitting and corrosion
- Excellent hand-tearability for fast manual assembly on coil production lines
Recommended Industrial Applications
Transformer coil winding, wire harness bundling, motor lead anchoring, acoustic anti-rattle cushioning
