PRODUCT DESCRIPTION LOCTITE EDAG 427 SS E&C provides the following product characteristics: Technology Thermoplastic Appearance Silver Cure Heat cure or Infrared Operating Temperaturecontinuous 149oC Product Benefits ● Screen printable ● Adheres well polyester film ● High solids for excellent coverage and easy film build Application Conductive Ink Typical Assembly Applications ● Membrane switches ● electroplating precoats ● RFI shielding ● printed antennas ● Flexible circuits ● Heating elements LOCTITE EDAG 427 SS E&C conductive screen printable ink consist of very finely divided silver particles dispersed in a thermoplastic resin . This is one of a series of EDAG products designed to provide controlled electrical properties. It can be used by itself or blended with EDAG 423 SS E&C (graphite) to allow significant cost savings in applications that do not require the extreme conductivity of silver alone. A ready-for-use blend of EDAG 427 SS E&C and EDAG 423 SS E&C is available as EDAG 426 SS E&C .
