Application Guide
Without thermal interface material, the heat flow go through joint face slowly, and the thermal conductive
performance is bad (Thermal conductivity of air is 0.026 W/m K). Using
T-Global Thermal Interface Material
to link two
joint faces, the heat flow go through equally, and the thermal conductive performance is good.
Materials Needed
•
Clean lint-free cloth rag
•
Industrial solvent
•
Rubber gloves
For optimal performance, T-Global Technology recommends interface flatness of 0.001 in/in (0.025 mm/25 mm) to
0.002in/in (0.050 mm/25mm) maximum.
Step 1:
Ensure that the surface is free from oil, dust, or any contamination that may affect bonding. Using rubber
gloves, wipe surfaces with a cloth dampened with industrial solvents such as MEK, toluene, acetone or isopropyl
alcohol.
Step 2:
Cut sheet to size and remove a liner or remove pre-cut sheet from roll.

Step 3:
Apply to center of heat sink bonding area and smooth over entire surface using moderate hand pressure /
rubbing motion. A roller may be useful to help smooth the part to the surface by rolling from the center out to beyond
the edges of the part. This ensures optimal contact between T69 sheet and heat sink.
Step 4:
Center heat sink onto component and apply using any one of the recommended temperature and pressure.
(Minimum: 10 psi at room temperature for 15 seconds.
Preferred:
30 psi at room temperature for 5 seconds)
More pressure equals better wetting out of the adhesive to the contact surfaces. A twisting motion during assembly
of the substrates will typically improve wetting.
Note that typically 70% of the ultimate adhesive bond strength is achieved with initial application, and 80-90% is
reached within 15 minutes. Ultimate adhesive strength is achieved within 36 hours; however the next manufacturing
step can typically occur immediately following the initial application.
