Name: DOW DOWSIL SE 4445 CV Thermally Conductive Gel Kit
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of DOW DOWSIL SE 4445 CV Thermally Conductive Gel Kit

Two-component, solvent-free silicone gel system offering excellent thermal conductivity and low modulus for stress-sensitive assemblies.
Self-leveling and non-slumping behavior ensures consistent gap-filling across irregular surfaces and varying bond line thicknesses.
Ultra-low compression force required—ideal for delicate components such as ceramic substrates, thin heat spreaders, and fragile semiconductor packages.
Excellent long-term stability with minimal pump-out or phase separation under thermal cycling (−40 °C to 150 °C).
Room-temperature cure capability with optional accelerated cure at elevated temperatures for high-throughput manufacturing.

Typical Applications Of DOW DOWSIL SE 4445 CV Thermally Conductive Gel Kit

Thermal interface material (TIM) between power electronics modules (e.g., IGBTs, SiC MOSFETs) and cold plates in electric vehicles and renewable energy inverters.
Die-attach and heat dissipation solution for high-brightness LEDs and laser diodes in automotive lighting and industrial sensing systems.
Gap-filling thermal management for 5G base station RF power amplifiers and millimeter-wave antenna modules.
Interface material for AI accelerator chips and high-performance computing (HPC) GPUs where mechanical compliance and reliability are critical.
