Thermally Conductive Grease

Thermally Conductive Grease


Tgrease 300X Series

High Performance Thermal Grease

Tgrease 300X is a silicone-based thermal grease for use in high performance CPUs and GPUs. Tgrease 300X has a high thermal conductivity of 3.0 W/mK and superior wetting characteristics, resulting in a very low thermal resistance and excellent long term reliability. Tgrease 300X has been formulated not to sag or drip with a high thixotropic index for ease of application and reliability.

• Low thermal resistance

• Excellent long term stability

• RoHS compliant

• Resists pump out through novel gel technology

• Available in 1kg (quart container), custom syringes

 Additional Product Description STORAGE
Store between 15 and 45C and a maximum humidity of 50%. Do not store in freezer or refrigerator below 5C.

Screen print using a mesh of 61 treads per inch (TPI) or less is recommended for easiest application, however the grease
has been successfully applied using up to a 140 TPI mesh (The higher the number = smaller mesh opening). If applying
from a can, mix can well prior to use. Dispense via syringe or cartridge by hand or mechanically.
