Smooth foil backings with
conductive adhesive
3M EMI Shielding Tapes 1170
(aluminum), 1181 (copper) and 1183
(tin-plated copper) are smooth-
backed foil tapes that establish
secure electrical contact with the
application surface by means of a
unique adhesive. Broadly distributed
conductive particles in the adhesive
provide a multitude of low-resistance
paths between the backing and the
substrate. (Figure 1)
Embossed foil backings
The backings of 3M Shielding Tapes
1245 (copper), 1267 (aluminum) and
1345 (tin-plated copper) are impressed
with an embossed pattern (Figure 2)
that protrudes through the acrylic
adhesive to make direct electrical
contact with the application surface.
This reliable “through-the-adhesive”
conductivity system provides stable
contact resistance and a high level of
shielding effectiveness.
Tin-plated foil backings
The copper used in 3M EMI Shielding
Tapes 1183 (smooth backing) and 1345
(embossed backing) is plated on both
sides with tin to provide excellent
solderability and resistance to
corrosion and oxidation. The tapes are
designed to remain conductive even
after oxidation.
Conductive adhesive
on both sides
3M Shielding Tape 1182 is a copper
foil tape coated on both sides
with conductive acrylic adhesive.
This unique construction offers an
excellent method of grounding and
bonding conductive surfaces. It also
exhibits low thermal resistance. 3M
tape 1182 is supplied with a removable
liner on each side for ease of handling.
Smooth foil backing with
nonconductive adhesive
3M Shielding Tape 1194 is a smooth-
backed copper tape that features the
same high quality solvent-resistant,
acrylic adhesive as other 3M foil
tapes. Good solderability makes it an
economical choice for applications
like connector and cable shielding,
grounding, electrostatic shielding
between transformer windings, outer
wrap for coils, and attachment of
connector tabs on rolled film-and-foil
capacitors.
Conductive fabric tape
3M Fabric Tape CN-3190 is an
anti-corrosion polyester ripstop
fabric backing with an electrically
conductive acrylic adhesive. It
provides effective copper-nickel
shielding with excellent flexibility and
conformability as well as light weight
and high strength.
Adhesive
Both the conductive and
nonconductive versions use the
same acid-free, corrosion-resistant
acrylic resin.

Tape Adhesives
Thermosetting Rubber (RT): Thermosetting rubber
adhesives have high initial adhesion and electrical
purity. When properly thermoset, a rubber-resin
adhesive system is designed to provide more
aggressive adhesion and bonding, higher solvent
resistance and higher heat resistance.
Acrylic (A): Acrylic adhesives have high solvent
resistance and do not require pre-baking or
thermosetting because they are made from synthetic
polymers specifically formulated to resist heat,
oxidation, solvents and oils, and exhibit acceptable
performance in many applications without a
cure cycle.
Silicone (ST): Silicone adhesive systems are perfect
for high temperature applications because they have
exceptional heat resistance, are inorganic, require
higher temperatures for the thermosetting reaction,
and, if burned, leave a nonconductive residue.
Product Shelf Life
All 3M Electrical Tapes have a 5-year shelf life
(excluding 3M 40 tape) following the date of
manufacture. It is 3M’s standard procedure to
ship any product with at least two years of its shelf life
remaining. Any special request for a specific shelf life
requirement may require a larger-than-stated
minimum order quantity (MOQ) that justifies a non-
scheduled product run. Contact your 3M sales
representative for specific shelf life and minimum
order quantity requirements. (No product returns will
be accepted on special shelf life request orders.)

Voltage Endurance
3M Inorganic Insulating Materials retain a
high percentage of dielectric strength even
after extended exposure to high operating
temperatures. They also will exhibit greater
voltage endurance under continuous electrical
stress than many other electrical insulation
materials, helping improve equipment reliability.
Thermal Conductivity
The high thermal conductivity of inorganic
papers helps achieve the heat dissipation
required in today’s high-efficiency electrical
apparatus, allowing the design of smaller,
more cost-effective equipment.
Varnish Absorption
The good varnish absorption
characteristics of inorganic paper
can enhance its already high thermal
conductivity, allowing equipment to run
cooler, quieter, and last longer.
Low Moisture Absorption
Manufactured with less than 1% moisture
content, inorganic papers exhibit low moisture
absorption even in humid environments. This
gives them dimensional stability and reduces
the need for extended drying cycles.
