Features and Benefits

Features	Benefits
Thermal Conductivity higher to 6W/mK Thermal Resistance lower to 0.03 °C·cm²/W	Excellent Thermal Management Performance
Custom-engineered Rheological Properties	Robust Processing Compatibility Compatible with Screen printing and automated dispensing process. Easy for manual or automated mixing, no dropping during screen printing or dispensing, smooth mesh release with out flow after application.
Resists premature drying after screen printing and prior to assembly	Service life exceeds 1 month at 85°C/85%RH; selected thermal grease grades achieve 2~3 months durability.
Stable post-assembly thermal performance, resistant to drying and pump-out	Long-term stable performance over device lifetime
Solvent-free formulation, compliant with RoHS and REACH requirements	Compliant with sustainability and EHS (Environment, Health & Safety) requirements
