LOCTITE® EDAG 440A E&C graphite polymer thick film material is formulated to provide conductive electronic traces in the manufacture of flexible circuitry. Much like its counterpart LOCTITE® EDAG 440B E&C, this carbon ink is compatible and can be overprinted onto LOCTITE® EDAG 725A silver conductor and other Henkel products. However, EDAG 440A is optimized for compatibility with more solvent-sensitive substrates like polycarbonate film and has a lower cure temperature than many functional inks.
