Features Of Dow DOWSIL EG-3810 Dielectric Gel

  1. Non-corrosive silicone-based formulation safe for sensitive electronic components and metals.

  2. Excellent dielectric strength (>20 kV/mm) for reliable electrical insulation in high-voltage environments.

  3. Thermally stable across a wide operating temperature range (–40 °C to +200 °C).

  4. Low volatility and non-migrating behavior ensure long-term performance without pump-out or dry-out.

  5. Easy-to-dispense, thixotropic gel consistency enables precise application and gap-filling without sagging.

Typical Applications Of Dow DOWSIL EG-3810 Dielectric Gel

  1. Insulation and protection of high-voltage connectors and terminations in EV powertrain systems.

  2. Dielectric filling for sensors, transducers, and automotive control modules exposed to thermal cycling.

  3. Encapsulation and potting of LED drivers and power electronics in outdoor lighting applications.

  4. Gap-filling between heat sinks and power semiconductors to enhance thermal management while maintaining electrical isolation.

  5. Protection of battery module interconnects and busbar joints in energy storage systems.
