| DOWSIL™ TC-5080 Thermal Grease Grey 1 KG |
| Product Overview |
| DOWSIL™ TC-5080 Thermal Grease Grey is a high-performance, non-curing silicone thermal grease heavily filled with thermally conductive metal oxides. Formulated to fill microscopic air voids between high-heat electronic components and heat sinks, it minimizes thermal resistance for maximum heat dissipation. Advanced filler architecture prevents slump, vertical bleed, and pump-out during continuous thermal cycling. It maintains its soft consistency, high thermal conductivity, and electrical insulation without drying out or hardening over time. The 1 kg can package offers an optimal size for stencil/screen printing, manual dispensing, and medium-scale electronic assembly. |
| Key Features and Benefits |
| • High Thermal Conductivity: Delivers superior heat transfer efficiency for high power-density CPUs, GPUs, and power electronics. • Low Thermal Impedance: Effectively wets surface micro-roughness to minimize contact thermal resistance. • Non-Curing Formulation: Will not dry out, crack, or harden, ensuring easy cleanability and reworkability during maintenance. • Pump-Out & Slump Resistance: Resists migration and displacement under severe thermal cycling and vertical mounting conditions. • Convenient 1 KG Can Packaging: Suited for stencil/screen printing processes and semi-automated dispensing lines. • Reliable Thermal Stability: Maintains performance integrity across severe operating temperature extremes. |
| Technical Specifications |
| • Appearance / Color: Grey paste • Packaging / Net Weight: Can / 1 KG • Chemical Base: Thermally Conductive Filled Silicone Compound (Non-curing) • Thermal Conductivity: ~3.0 - 4.0 W/m.K class • Specific Gravity (@ 25°C): ~2.6 g/cm³ • Service Temperature Range: -45°C to +150°C (-49°F to +302°F) |
| Applications |
| • Thermal interface material (TIM) for high-performance CPUs, GPUs, chipsets, and memory modules. • Automotive power electronics, inverters, DC-DC converters, and battery management systems (BMS). • High-brightness LED fixtures, power supplies, telecommunications base stations, and server racks. • Electronic assemblies requiring high thermal conductivity and a non-curing grease interface. |
Usage Note: Ensure all mating surfaces are clean, dry, and free of oil or contaminants before application. Applying a thin, uniform layer via stencil printing or spatula is sufficient to minimize thermal resistance. Keep container tightly sealed when not in use.
