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
measures only a few milliohms.
