3M™ Thermal Grease
3M™ Thermally Conductive Interface Pads: Silicone or Acrylic Elastomers
3M™ Hyper-Soft Thermally Conductive Interface Pads are used to transfer heat from a hot surface
or device to a cooler surface region of the assembled design. The 3M Thermally Conductive pads
are available in a silicone elastomer version or an acrylic elastomer version where a non-silicone
base material is desired. The pads are designed in a variety of thermal conductivities and softness
grades to provide excellent gap filling, low assembled stress and a high degree of wet-out for more
efficient heat transfer.
3M™ Thermally Conductive Epoxies
This range of liquid adhesives has minimal odor and superior structural adhesion strength.
Dispensing is easy for high output, in-line automated manufacturing and manual application
Adhesive flows and fills micro-spaces on surfaces. Ultra-thin bond line helps achieve low
thermal impedance.
3M Thermally Conductive Adhesive Transfer Tapes
™
This range of high adhesion thin tapes offers efficient thermal transfer for a wide range of
applications requiring a thermal management solution: bonding heat sinks, heat spreaders and
other cooling devices to IC packages, power transistors, and other heat generating components.
Each tape combines 3M high performance acrylic adhesive with highly conductive ceramic
particles for an extremely reliable and user-friendly thermal interface. Highly conformable
construction provides excellent wet-out on surfaces.
3M™ Thermally Conductive Grease
The 3M™ Thermally Conductive Greases are high performance thermal interface materials for
transferring thermal energy from a heat source (e.g. processor chip, graphics chip, High Power
LED) to a heat sink. The proprietary blend of inorganic fillers contained in an organic matrix
(non-silicone) ensures high thermal conductivity and low thermal resistance. Grease products
are available in two versions: Standard viscosity and a lower viscosity version that can be useful
in screen printing application methods.

thermal pad.
TCG-2035/TCG-2031*
TCG-2037/TCG-2033*
Thermally conductive greases provide a thin thermal interface to optimize thermal heat transfer between hot
running devices and heat sinking surfaces. Excellent flow properties for improved interface wet-out.
* 3M Greases TCG-2031 and TCG-2033 are supplied with a small wt%
of a solvent added to lower viscosity. Lower viscosity can allow for reduced
thickness during application and may benefit screen printing options.
Effective thermal measurements are not significantly different from
non-solvent added versions. Shear Rate viscosity reduced by 5-10x.

Note: * 3 M Tape 9889FR is a specialty tape used for very large panels or surfaces where a very conformable thermal tape is needed to achieve good wet-out/adhesion. The 3M Tape 8820 is the suggested
standard TCATT Thermal tape for most typical, somewhat larger surface areas as the thermal impedance is lower vs the 3M Tape 9889FR.
**End use application testing will determine final temperature range based on final design and other environmental conditions. Suggested Temperature range is based on a UL-746 Test Method or
a 3M Test Method.
*** TM-67X tapes are designed with a high/low adhesion construction. Face side or non-liner side when product roll is unwound is the lower adhesion side.

* Notes: 1) Thermal Conductivity (TC) can vary in an application as the filler is a Boron Nitride (BN) platelette shape and alignment of fillers can change effective TC.
2) As the 3M™ Thermally Conductive Epoxy Adhesive TC-2707 uses aluminum metal fillers, under certain end use application conditions, the effective resistivity and/or effective dielectric strength
could be significantly lower than noted. If the metal fillers are “trapped” or “pinched” between two surfaces, an electrical bridge path via the aluminum fillers could occur between these surfaces.
Epoxy Adhesive TC-2707 is not suggested for applications where a powered electrical circuit is used or where a reliable volume resistivity and/or dielectric strength is desired. 3M Thermally
Conductive Epoxy Adhesives TC-2810 uses ceramic filler and is suggested product to test for these types of application performance needs.
**End use application testing will determine final temperature range based on final design and other environmental conditions. Suggested Temperature range is based on a UL-746 Test Method
or a 3M Test Method.
