Technical Data | October 2016 3M™ Thermally Conductive Silicone Interface Pad 5519 Product Description 3M™ Thermally Conductive Silicone Interface Pad (TCSIP) 5519 is designed to provide a preferential heat transfer path between heat generating components and heat sinks, heat spreaders or other cooling devices. 3M TCSIP 5519 consists of a highly conformable and slightly tacky silicone elastomer sheet filled with thermally conductive ceramic particles, which helps provide enhanced thermal conductivity and excellent electrical insulation performance. Key Features • • • • • • • Very high thermal conductivity and good electrical insulation properties Good softness and conformability even to non-flat surfaces Good electrical insulation properties Good flame retardant, UL94 V-0 equivalent material Compression relaxation properties help reduce pressure to electric components Slight tack allows pre-assembly Good wettability for improved and lower thermal resistance Product Construction/Material Description Note: The following technical information and data should be considered representative or typical only and should not be used for specification purposes. 3M™ Thermally Conductive Silicone Interface Pad 5519 Property Color Base resin Thickness Primary Filler Type Product Liner Value White Silicone 0.5 – 2.0mm* Ceramic PET Film Liner * Standard thickness range.

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. • 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.
