OPUTE 1 W/m·K Thermal Putty for Electronic Gap Filling and Heat Dissipation
TC-10 Silicone Thermal Putty
OPUTE TC-10 is a single-component, thixotropic silicone-based thermal putty formulated with metal oxides and silicone resin. With a thermal conductivity of 1.0 ± 0.2 W/m·K, it is designed to fill air gaps and uneven interfaces between heat-generating electronic components and heat sinks. The material remains soft over time and offers electrical insulation, water resistance, low oil separation and low volatility.
Key Features & Benefits
- Thermal Gap Filling: Fills gaps and irregular surfaces between heat sources and heat sinks to improve thermal contact.
- Single-Component Formula: Ready for application without A/B component mixing.
- Soft & Thixotropic: Maintains a soft consistency over time and conforms to uneven surfaces.
- Low Oil Separation: Oil separation of ≤1% after 24 hours at 150°C.
- Low Volatility: Volatile content of ≤0.2% after 24 hours at 150°C.
- Electrical Insulation: Volume resistivity of ≥1.0 × 10⁸ Ω·cm.
- Water Resistance: Silicone-based formulation with water-resistant properties.
Applications
TC-10 is intended for thermal gap filling between electronic heat sources and heat sinks. Typical components identified in the TDS include:
- Integrated circuits (ICs)
- Transistors and electronic power components
- Processors and electronic assemblies
- Heat sources and heat sinks
- Uneven mating surfaces requiring thermal gap filling
Customers should verify thermal performance and material compatibility under actual assembly conditions before mass production.
