Gels are a special class of encapsulants that cure to an extremely soft material. They are used to provide high levels of stress relief to sensitive circuitry. Gels perform many important functions in electronics. Their major job is to protect electronic assemblies and components from adverse environments by:
  • Functioning as dielectric insulation
  • Protecting the circuit from moisture and other contaminants
  • Relieving mechanical and thermal stress on components
