Features Of Dow DOWSIL 3-4154 Dielectric Gel Kit

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

  2. Thixotropic gel consistency provides excellent gap-filling and stays in place without slumping or migration.

  3. Wide operating temperature range from −40 °C to +200 °C for reliable performance in demanding environments.

  4. High dielectric strength (>20 kV/mm) and low electrical conductivity ensure effective electrical insulation.

  5. UL 94 V-0 rated for flame resistance, supporting compliance with stringent safety standards.

Typical Applications Of Dow DOWSIL 3-4154 Dielectric Gel Kit

  1. Insulation and protection of high-voltage battery module connections in electric vehicles (EVs).

  2. Dielectric filling for power electronics enclosures, including inverters, converters, and onboard chargers.

  3. Thermal interface and electrical isolation in LED lighting drivers and industrial power supplies.

  4. Moisture and contamination barrier for outdoor telecom junction boxes and renewable energy control units.
