Main features
- 1.8 W/(m K) Thermal Conductivity
- One-Component 100% Solids Non-Slump RTV
- -50 to 230 deg C Operating Range
Product Description
Electrolube® TCOR is a single-component, 100% solids, low-odour silicone RTV formulated to improve heat transfer between electronic devices and heat sinks. The white, non-slump paste cures through exposure to atmospheric moisture and combines a thermal conductivity of 1.8 W/m·K with adhesive, sealing, and gasketing capabilities. Once cured, TCOR supports an operating temperature range of -50 to 230 °C, with a maximum operating temperature of 250 °C for 30 minutes. Its high-viscosity consistency allows controlled placement around components and power resistors where thermal dissipation and material retention are required.
Key features
- Thermally conductive: Provides a typical cured thermal conductivity of 1.8 W/m·K using the supplier's heat-flow measurement method.
- Single-component non-slump paste: Requires no component mixing and maintains its applied form during placement.
- Wide operating temperature range: Supports cured-material use from -50 to 230 °C, with short-term exposure to 250 °C for 30 minutes.
Applications / Suitable for
- Interfaces between electronic devices and heat sinks
- Thermal dissipation around electronic components
- Thermal management around power resistors
- Low-bond-strength thermal adhesive, sealant, or gasketing applications
