CoolTherm® TC-404 Thermally Conductive Grease Where to Buy
Product Information
LORD CoolTherm® TC-404 thermally conductive grease is a non-reactive, solvent-free silicone material designed for applications where a highly conductive thermal interface material is required and where the device may later need to be easily removed from the heat sink.
Shelf Life
• Material Stored in Syringe
Shelf life is six months from date of manufacture when stored at -30°C in original, unopened syringe. Syringe must be maintained at -30°C in a vertical (upright) position with the dispense tip facing down. Do not store syringe on its side (horizontally).
This material is shipped and stored frozen. Consult handling instructions** for thawing.
• Material to be Remixed
Shelf life is six months from date of manufacture when stored at 25°C in original, unopened container.
** Handling instructions are available on LORD.com.
Features and Benefits
High Thermal Conductivity – provides thermal conductivity for applications where superior heat dissipation is required.
Reworkability – easily removed with isopropyl alcohol or acetone, eliminating the use of toxic solvents.
Thin Bondlines – achieves thin bondlines of ≤1 mil, minimizing the thermal pathway and maximizing heat flow.
High Reliability – provides excellent resistance to moisture and temperature cycling; low bleed.
