GCS-046-SM8H

GCS-046-SM8H is a high-performance silicone-based thermal grease designed to enhance heat transfer between components and heat sinks. With a thermal conductivity of 4.6 W/m K and extremely low thermal impedance (<0.0007 °C-in²/W), it ensures efficient cooling in electronic devices.

This grey thermal compound is easy to apply and spreads smoothly between surfaces. Its high viscosity (70,000 cps) allows it to stay in place without dripping or running, even when exposed to heat. It fills microscopic air gaps and irregularities, creating an optimal thermal path for heat dissipation.

GCS-046-SM8H operates across a wide temperature range, from -30°C to +300°C. This makes it suitable for use in demanding environments, including power electronics, CPUs, GPUs, LED modules, and industrial control systems.

The grease has a specific gravity of 2.94, giving it a dense, stable consistency. It maintains performance over time, resisting drying out or degradation. Its high stability ensures long-term reliability without frequent reapplication.

GCS-046-SM8H is RoHS compliant and safe for use in environmentally regulated industries. It comes in multiple sizes to suit different needs, including 20g and 30g syringes for precision application, and a 1kg pot for high-volume use. The product has a 24-month shelf life when stored properly.

This thermal grease is ideal for engineers who need a simple yet powerful solution for thermal management. It improves cooling efficiency, reduces thermal resistance, and protects components from overheating.

In summary, GCS-046-SM8H delivers strong thermal conductivity, stability, and ease of use. Whether in small electronics or large industrial systems, it provides reliable, long-lasting performance for high-efficiency thermal transfer applications.
