Name: Dow DOWSIL EG-4131 Dielectric Gel Kit
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Dow DOWSIL EG-4131 Dielectric Gel Kit

Non-corrosive, silicone-based formulation designed for long-term stability in sensitive electronic environments.
Ultra-low volatility and minimal outgassing, meeting stringent NASA ASTM E595 requirements for space-grade applications.
Excellent dielectric strength (>20 kV/mm) with stable performance across wide temperature range (–50 °C to +200 °C).
Thixotropic gel consistency ensures no slump or migration after application, even on vertical or inverted surfaces.
Ready-to-use two-component kit with precise 1:1 mix ratio—no weighing or complex metering required.

Typical Applications Of Dow DOWSIL EG-4131 Dielectric Gel Kit

High-voltage insulation and potting of power electronics modules, including IGBTs and inverters.
Dielectric filling for aerospace avionics enclosures and satellite thermal management systems.
Protection of high-frequency RF connectors and microwave components against moisture ingress and arcing.
Gap-filling encapsulation for LED drivers and EV battery control units requiring thermal stability and electrical isolation.
