Qnity Tgrease™ 3000 Thermal Grease

Introduction

Laird Qnity Tgrease™ 3000 is a high-performance silicone-based thermal grease designed to improve heat transfer between heat-generating electronic components and cooling hardware. It helps reduce thermal resistance at component interfaces, supporting dependable operation in demanding thermal environments.

Part Description

Tgrease™ 3000 is a thermally conductive grease formulated with conductive fillers in a silicone-based carrier. It offers a bulk thermal conductivity of 3.2 W/mK, making it suitable for transferring heat from semiconductor packages, modules, and other electronic surfaces into heatsinks, cold plates, or chassis-mounted cooling systems.

The grease requires no curing, allowing it to be applied and used immediately during assembly or maintenance. Its low pump-out characteristics help maintain thermal interface performance through thermal cycling, vibration, and long-term operation. With an operating temperature rating up to +200°C, it can support many high-power electronic and industrial designs.
