Product Introduction
Momentive SILCOOL™ TIG4090 is a thermally conductive silicone compound designed to deliver extra-low thermal resistance and high thermal conductivity. Its excellent workability makes it suitable for automated dispensing, screen-printing, and stamping processes. With minimized oil bleeding under harsh operating conditions, TIG4090 maintains stable grease properties, providing durable and efficient heat-transfer performance for advanced electronic designs.
Momentive SILCOOL™ TIG4090 Features
- Very thin BLT contributing to exceptionally low thermal resistance
- High volume resistivity and dielectric strength; electrically insulative
- Good workability for automated dispensing, screen printing, and stamping
- Solvent-free formulation; stable at room temperature and elevated temperatures
- Minimized oil bleeding for long-term grease stability
Momentive SILCOOL™ TIG4090 Applications
- Thermal interfaces in high-frequency and miniaturized electronics
- Heat dissipation for power-generating components
- Thin bond line thermal interface designs
- Screen-printed and dispensed thermal interface materials
