3M™ Thermally Conductive Silicone Interface Pad 5586
Product Description
3M™ Thermally Conductive Silicone Interface Pad 5586 is designed to provide a preferential heat transfer path
between heat generating components and heat sinks, heat spreaders or other cooling devices. 3M pad 5586 consists of
a highly conformable and slightly tacky silicone elastomeric sheet filled with thermally conductive ceramic particles that
provide enhanced thermal conductivity and excellent electrical insulation performance.

Application Techniques
Substrate surfaces should be clean and dry prior to the thermal pad application to ensure best thermal performance.
A clean surface can improve the thermal performance of an application.
•
Isopropyl alcohol (isopropanol) applied with a lint-free wipe or swab should be adequate for removing surface
contamination such as dust or fingerprints. Do not use “denatured alcohol” or glass cleaners, which often
contain oily components. Allow the surface to dry for several minutes before applying the thermal pad. More
aggressive solvents (such as acetone, methyl ethyl ketone (MEK) or toluene) may be required to remove heavier
contamination (grease, machine oils, solder flux, etc.) but should be followed by a final isopropanol wipe as
described above.
Note:
Be sure to read and follow the manufacturers’ precautions and directions when using solvents.
•
Apply the thermal pad to one substrate at a modest angle with the use of a squeegee, rubber roller or finger
pressure to help reduce the potential for air entrapment under the thermal pad during its application.
•
Remove the release liner before application.
•
Assemble the part by applying compression to the substrates to ensure a good wetting of the substrate surfaces
with the thermal pads. Rigid substrates are more difficult to assemble without air entrapment as most rigid parts
are not flat. Flexible substrates can be assembled to rigid or flexible parts with much less concern about air
entrapment because one of the flexible substrate can conform to the other substrates during application.
