Features Of Dow DOWSIL TC-3015 Thermal Gel

  1. Ultra-low modulus enables stress-free thermal interface performance under thermal cycling.

  2. Non-silicone-oil bleeding formulation ensures long-term stability and prevents contamination of adjacent components.

  3. Excellent conformability to irregular surfaces and low-height gaps (down to 0.1 mm).

  4. Thermally stable across -40 °C to 150 °C operating range with minimal degradation over time.

  5. Re-workable and non-curing — maintains tack and conformability throughout device lifetime.

Typical Applications Of Dow DOWSIL TC-3015 Thermal Gel

  1. High-power LED modules requiring reliable heat dissipation in automotive lighting systems.

  2. Power electronics in electric vehicle (EV) inverters and onboard chargers.

  3. 5G base station power amplifiers and RF semiconductor packages.

  4. AI accelerator and GPU cooling assemblies in data center servers.

  5. Industrial motor drives and renewable energy inverters for solar/wind applications.
