3M™ Electrically Conductive Cushioning Gasket Tape
ECG-8035 / ECG-8055 / ECG-8075
Product Description
3M™ Electrically Conductive Cushioning Gasket Tapes ECG-8035 / ECG-8055 / ECG-8075 are electrically conductive
compressible gasket tapes in a double coated tapes format with good electrical conductivity and excellent cushion/
recovery properties. The 3M ECG-8035 / ECG-8055/ ECG-8075 offer excellent gap filling performance while
maintaining good electrical grounding potential. These products offer conductivity through the thickness (Z-axis) and in
the plane of the adhesive (X-Y planes) and are ideal for EMI/EMC gasket tape applications between common substrates,
such as metal surfaces (including metal plated substrates). These products consist of a soft and conductive polymeric
foam gasket and thin electrically conductive adhesive tapes laminated on both sides of the cushion gasket. The
conductive adhesive is a high performance 3M™ Electrically Conductive Adhesive Transfer Tape (ECATT).
The 3M ECG-8035 / ECG-8055/ ECG-8075 Tapes are useful for EMI/ RFI shielding & grounding in electronics and
electrical devices. The 3M ECG-8035/ ECG-8055/ ECG-8075 may be applied in strips or die cut to specific shapes and
sizes. Compared to screws or other mechanical connectors and grounding means, the 3M ECG-8035 / ECG-8055/ ECG-
8075 products can provide for reduced assembly time and excellent conformability to the space between substrates,
excellent bond line gap filling which will allow for enhanced EMI shielding and reduced EMI emissions. The 3M ECG
products are EMI and grounding gaskets and provide for excellent grounding and EMI shielding. The 3M ECG products
are of an “open cell” design and thus their “environmental” gasket performance will be limited and must be tested by an
end user to see if it meets their environmental sealing requirements (dust, moisture, water, etc.). The 3M ECG products
could be used in conjunction with products that are non-conductive and provide for the “Environmental Sealing” if desired
(ex: 3M™ VHB™ Tapes).
3M ECG-8035 / ECG-8055/ ECG-8075 are supplied in a dual sided removable liners configuration for easy handling and
die-cutting properties. 3M ECG-8035 / ECG-8055/ ECG-8075 are available in standard size and custom sizes (widths and
lengths).

Application Techniques
• To obtain maximum adhesion, the bonding surfaces must be clean and dry. Isopropyl alcohol is recommended as a
cleaning solvent.*
• Bond strength is dependent upon the amount of adhesive-to-surface contact developed during application. The wetted
contact area can be increased by applying 3M™ Electrically Conductive Cushioning Gasket Tapes ECG-8035 / ECG-
8055 / ECG-8075 firmly with a roller or finger pressure to exclude air entrapment. Adhesion is optimized when the
substrates are flat or conformable substrates.
• Electrical performance is dependent upon the nature of the substrate surface finish and surface type (Stainless steel,
Aluminum, etc.). Most metal surfaces give enhanced electrical performance with 3M ECG-8035 / ECG-8055/ ECG-8075
when the surface has been lightly abraded and cleaned. Scotch-Brite™ Pads are suggested for preparing the metal surface.
• 3M ECG-8035 / ECG-8055/ ECG-8075 should be applied between 17°C - 35°C. Tape application below 10°C is not
suggested because the adhesive will be too firm to wet the substrates, resulting in low adhesion. Warming the substrates
to 38°C facilitates adhesion. Once properly applied, low temperature holding power is generally satisfactory.
• 3M ECG-8035 / ECG-8055/ ECG-8075 can be removed by separating the parts using torque for rigid parts or peel for
flexible ones. Remove the adhesive by pulling off as much as possible by hand is suggested. Residual adhesive may be
removed by rubbing with your finger or by application of 3M™ Packaging Tape over the residual adhesive followed by
removal of the packaging tape. The surfaces should be cleaned again before applying a new piece of 3M ECG-8035 /
ECG-8055/ ECG-8075. The force required to separate the parts and/or remove the adhesive can be reduced by softening
the adhesive by heating to 70°C - 100°C or using solvents such as acetone.*
*Note: Carefully read and follow the manufacturer’s precautions and directions for use when handling cleaning solvents.

General Information
3M™ Electrically Conductive Cushioning Gasket Tapes ECG-8035 / ECG-8055 / ECG-8075 provide good adhesion to
most metal surfaces and provides good electrical resistance to many substrates. The pressure sensitive nature and fiber
reinforcement of 3M ECG-8035 / 8055 / 8075 make this product convenient to use and 3M ECG-8035 / ECG-8055/
ECG-8075 also have very good handling properties including good liner release.
Application Ideas
• 3M™ Electrically Conductive Cushioning Gasket Tapes ECG-8035 / ECG-8055 / ECG-8075 are typically used for
applications requiring excellent EMI shielding, flexibility/gap filling in the bond line, contact grounding and a
mechanical cushion to protect from mechanical shock/vibration in the electronic devices.
• Grounding Mobile Hand Held and Flat Panel Display
• Key pads and display modules in Mobile Hand Held devices and Flat panel display as LCD and PDP need to be
electrically attached to the grounding mechanism.
• Assembly of EMI Cage, Metal Case and Frame in Modern Electronic Devices and High Speed Telecommunication
Equipment.
• Assembly of cover case and main frame parts
• EMI cage to PCB (printed circuit board). The EMI cages are typically constructed from aluminum frames and lids to
protect components on the PCB from EMI/RFI. 3M ECG-8035 / ECG-8055/ ECG-8075 are applied as a die cut in the
shape of the perimeter, then the frame is bonded to the perimeter trace.
