1182 Tap e
Copper Foil Conductive Adhesive on Both
Sides
Data Sheet
Product Description
3M 1182 Tape consi s ts of a 1-ounce dea dsoft
coppe r foil backi ng that is coated on both si des
with a uni que electri ca lly conducti ve pressure-
sensit ive acr yli c adhesive.
• Deadsoft 1-ounce c opper foil bac ki ng
• Conductiv e ac ryl i c adhe si ve on both sides
• Supplied with rem ova ble liner on both sides for
easy handling and di ec utti ng
Like al l 3M shieldi ng tape s, 3M 1182 is availabl e
in sta ndard and custom widths a nd le ngths.
Standard length is 18 yards.
• Widths f r om 1/ 4” to 23”
• Longer lengths up to seve ral times normal
le ngth, depende nt upon w i dth. Check with
Customer Service.
Applications
3M 1182 is typica lly use d to bond two surfaces
together, both electrically and physically. An
exa mple would be adheri ng a conductive ga sket
to a conduc ti ve surface as part of the EMI
shie l di ng sol ution for an electroni c e nclosure.
Conductivity
Sinc e 3M 1182 double- si ded copper tape would
typically be used as an electrical path between
two surfaces, its most important feature is its
conduc tivi ty. Highly conduc ti ve par ti c le s i n the
acrylic adhesive provide a m ul titude of electri ca l
paths between the ap plica ti on substrate and the
surface of the copper foil on each side. The
resi stance of the conductive path through the
adhesive (measured over a 1-in2 area) typically
measures only a few milliohm s.
