1182 Tape
Copper Foil Conductive Adhesive on Both
Sides
Data Sheet
Product Description
3M 1182 Tape consists of a 1-ounce deadsoft
copper foil backing that is coated on both sides
with a unique electrically conductive pressure-
sensitive acrylic adhesive.
• Deadsoft 1-ounce copper foil backing
• Conductive acrylic adhesive on both sides
• Supplied with removable liner on both sides for
easy handling and diecutting
Like all 3M shielding tapes, 3M 1182 is available
in standard and custom widths and lengths.
Standard length is 18 yards.
• Widths from 1/4” to 23”
• Longer lengths up to several times normal
length, dependent upon width. Check with
Customer Service.
Applications
3M 1182 is typically used to bond two surfaces
together, both electrically and physically. An
example would be adhering a conductive gasket
to a conductive surface as part of the EMI
shielding solution for an electronic enclosure.
Conductivity
Since 3M 1182 double-sided copper tape would
typically be used as an electrical path between
two surfaces, its most important feature is its
conductivity. Highly conductive particles in the
acrylic adhesive provide a multitude of electrical
paths between the application substrate and the
surface of the copper foil on each side. The
resistance of the conductive path through the
adhesive (measured over a 1-in
2
area) typically
measures only a few milliohms.
