Single Component Thermally Conductive Adhesive​ Dowsil SE4486 Non Corrosive

Product Overview​​

​​Dowsil SE 4486​​ is a ​​non-corrosive, single-component, moisture-cure silicone thermal adhesive​​ designed for high-performance thermal management in electronics. Its unique formulation ensures rapid curing, low volatility, and exceptional thermal conductivity, making it ideal for bonding heat-sensitive components in demanding environments.

Product Introduction​​

SE 4486 is engineered to address critical thermal challenges in modern electronics. As a ​​flexible elastomer​​ post-cure, it provides reliable stress relief and vibration damping across a wide temperature range (-45°C to 200°C). Its ​​controlled volatility​​ (D4-D10 <0.002) minimizes outgassing risks, protecting sensitive components during operation. Engineered for fast tack-free performance, this adhesive is compatible with automated dispensing systems, enhancing production efficiency.

Enhanced Properties

Ultra-Low Volatility​​: Meets stringent requirements for emissions-sensitive applications (D4-D10 <0.002).

High Thermal Conductivity​​: Delivers efficient heat transfer (1.53 W/m·K at 25°C) to dissipate heat from power devices.

​​Rapid Curing​​: Achieves tack-free surface in under 4 minutes at room temperature, accelerating production cycles.

Mechanical Flexibility​​: Shore A hardness of 78 ensures shock absorption and reliability under thermal cycling.

​​Electrical Insulation​​: Maintains dielectric integrity with a UL 94 V-0 flammability rating.

Application Scenarios​​

SE 4486 is widely used in industries requiring robust thermal management solutions:

​​Power Electronics​​: Bonding heat sinks to IGBT modules, DC-DC converters, and power transistors.

​​LED Lighting​​: Securing LED chips to substrates while preventing thermal runaway.

​​Automotive Electronics​​: Protecting automotive ECUs, inverters, and battery modules from heat stress.

​​Consumer Electronics​​: Ideal for smartphone PCBs, gaming consoles, and wearable devices.
