with Double Coated Electrically Conductive Acrylic Adhesive
Data Sheet
Product Description
June 2021
3M™ EMI Copper Foil Shielding Tape 1182 is a 3.5-mil (0.089 mm) thick tape composed of a
1.4-mil (0.036 mm) flat copper foil backing coated on both sides with a non-corrosive,
electrically conductive acrylic pressure-sensitive adhesive supplied on a removeable liner.
Commonly used for bonding two surfaces together, both physically and electrically
Provides low z-axis resistance connection between substrates
Can be die-cut and offers a multitude of uses in electrical design and test laboratories for
prototyping, design and troubleshooting.
Adhesive requires no moisture, solvents, heat or other manner of preparation to affect
application

Effectiveness
Many factors determine the true shielding effectiveness of a shielding tape, including type and
thickness of foil, adhesive type, intimacy of contact, smoothness of application surface,
frequency of the EMI signal, etc.
