3M™Thermally Conductive Grease TCG-2037 / TCG-2033
Product Description
3M™ Thermally Conductive Grease TCG-2037 is a high performance thermal interface material for transferring thermal
energy from a heat source (e.g.: processor chip, graphics chip, etc.) to a heat sinking or heat spreading surface. The 3M
Grease TCG-2037’s blend of inorganic fillers in a non-silicone resin system provides for excellent bulk thermal
conductivity along with very low thermal resistance.
3M™ Thermally Conductive Grease TCG-2033 has a lower viscosity versus the 3M™ Thermally Conductive Grease
TCG-2037 as a small amount of solvent has been blended into the product. The lower viscosity of the 3M Grease
TCG-2033 can allow for a thinner bond line leading to improved thermal resistance and is also designed for use in
screen printing applications.
Key Features
• Superior bulk conductivity.
• Non-silicone based formulation.
• Excellent thermal impedance.
• < 40 µ max particle diameter.
• 3M Grease TCG-2033 is screen printable.

Storage and Shelf Life
Product Shelf life is 9 months from date of manufacture when stored in the original product container and packaging
materials and stored at room temperature (18-24°C) and 50% RH.
To ensure best uniformity of conductive fillers, the product should be mixed prior to use to ensure uniform distribution of
fillers.
Directions for Use
Apply the product at the desired interface and use pressure (from approximately 1-25 psi applied at a variable or constant
force as determined by end user) when bringing the substrate interfaces together. Pressure is applied until the desired gap
thickness is achieved. Apply sufficient product to ensure good gap filling at the desired final nominal gap thickness
(Sufficient product volume use can be demonstrated by having a small amount of squeeze-out at the edges of the interface).
Heat can be applied (40-50°C) to lower the product viscosity to aid in product flow and for establishing a desired gap
thickness.
The 3M™ Thermally Conductive Grease TCG-2033 product contains a small amount of solvent to lower viscosity and
allow for screen printing. Screen print to a desired surface and allow product to rest open faced for 2-10 minutes at room
temperature to allow solvent to evaporate prior to assembly. Review MSDS for detailed use information.
