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.
