SILCOOL TIA208R is a two-component thermally conductive silicone potting compound by Momentive Performance Materials. It cures to a thermally conductive rubber with primerless adhesion to metals and plastics, conforms to complex 3D cavities, and is UL94 V-0 certified (File E320603) with a 150°C RTI rating.
Features & Benefits
- UL94 V-0 certified (File No. E320603) and 150°C RTI for flame-retardant electronic potting
- Primerless adhesion to most metals and plastics — simplifies production process
- 90-minute work life provides ample handling time before cure
- Room temperature or heat-accelerated cure (70°C × 30 min) for production flexibility
- Conforms to complex 3D shapes and cavities for void-free thermal paths
- Good electrical insulation: 1.0×10¹⁴ Ω·cm volume resistivity, 25 kV/mm dielectric strength
Typical Applications
- Thermal potting of power supplies and LED drivers
- Potting of electronic ballasts and control modules
- Gap filling in power electronics requiring UL94 V-0 flame retardancy
- Thermal management of automotive ECUs
