Elan-tron® MC 4539 / W 4539 is a two-component, filled epoxy potting system designed for encapsulation, sealing, and impregnation of electrical and electronic components. The compound is self-extinguishing, UL 94 V-0 certified (File E143115, E116643), and RoHS compliant. With high thermal conductivity, excellent dielectric strength, and robust mechanical performance, it offers protection under high thermal loads (thermal class H, 180°C). The resin–hardener system provides low shrinkage, reliable adhesion, and enhanced resistance to thermal and mechanical stress, making it highly effective for long-term electrical insulation and protection.
Encapsulation of electronic modules
Sealing and impregnation of electrical parts
Potting of components requiring flame resistance and thermal conductivity
Suitable for both manual and automatic vacuum casting processes
