Electrical Potting and Encapsulating Compounds

Advanced Technology Epoxy Potting and Encapsulation Systems

Advanced Technology Epoxy Potting and Encapsulation SystemsSOLAR COMPOUNDS CORPORATION is a manufacturer of advanced technology Epoxies, Urethanes and RTV Silicones for electrical potting and encapsulating, adhesives, coating and sealants.

Potting compounds are pourable insulating resins (epoxies, silicones, urethanes and hybrids) to be cast into cavities containing electronic components to insulate, protect, and hold them in place thus protecting components from shock and vibration.

Flame Retardant and High Thermal Conductivity Products

Solar potting and encapsulating compounds are formulated for the demanding high performance requirements of the electrical and electronic industries for such applications as the potting of HID electronic ballasts, capacitors, power supplies, relays and other devices with high heat dissipation requirements. Solar FR (Flame retardant) and HTC (High Thermal Conductivity) products provide higher flame retardancy, increased high-voltage insulating characteristics and improved thermal management over currently available materials, significantly reducing the operating temperature of potted internal components - thus extending the life cycle of electrical devices.

For users who want a soft, rubbery, low stress cure, yet need to operate at high temperatures and want to avoid using problematic polyurethanes, Solar offers soft-cure epoxies, RTV Silicones and unique hybrid polymers.
