Name: Dow DOWSIL 3-4222 Dielectric Gel Kit
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Dow DOWSIL 3-4222 Dielectric Gel Kit

Non-corrosive, silicone-based formulation safe for sensitive electronic components and metals.
Excellent dielectric strength (>20 kV/mm) for reliable electrical insulation under high-voltage conditions.
Thixotropic gel consistency ensures no sagging or migration after application, even in vertical or overhead assemblies.
Wide operating temperature range from –55 °C to +200 °C, maintaining stability across thermal cycling.
Low volatility and non-yellowing properties ensure long-term optical clarity and performance retention.

Typical Applications Of Dow DOWSIL 3-4222 Dielectric Gel Kit

Insulation and protection of high-voltage connectors in electric vehicle (EV) powertrain systems.
Dielectric filling for LED module housings and automotive lighting assemblies.
Gap-filling encapsulation of power electronics, including IGBT modules and DC-DC converters.
