Features Of Dow DOWSIL EG-4000 Kit Dielectric Gel

  1. Non-corrosive, silicone-based formulation safe for sensitive electronics and metal contacts.

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

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

  4. Low volatility and non-migrating—maintains consistent performance without drying out or bleeding.

  5. Easy-to-apply two-part kit (Part A + Part B) with controlled pot life and room-temperature cure.

Typical Applications Of Dow DOWSIL EG-4000 Kit Dielectric Gel

  1. High-voltage connector and busbar encapsulation in EV powertrains and battery systems.

  2. Insulation and environmental protection of sensors and control modules in industrial automation.

  3. Dielectric filling for LED driver housings and power supply assemblies.

  4. Sealing and insulation of photovoltaic junction boxes and solar inverters.

  5. Protection of aerospace avionics interfaces exposed to thermal cycling and humidity.
