PPG now offers a full line of electrically conductive, resistive and dielectric inks and conductive coatings for radio-frequency interference/electromagnetic interference (RFI/EMI) suppression. These inks and coatings are used in diverse applications such as:
• touch-control panels for smartphones, tablets and other consumer devices;
• interactive and electro-chromic displays;
• printed keypads and other industrial membrane switch controls;
• radio-frequency identification (RFID) tags; and
other products that require printed circuitry.
Conductive polymer thick film (PTF) inks, which are typically formulated with a metallic flake or powder to carry a charge and bound with a thermoplastic resin, can be printed on polymer-based film, polycarbonate, paper and other substrates. PTF inks are compatible with most printing methods, from flatbed and rotary-screen printing and flexography to rotogravure, as well as tampo (pad) and inkjet printing.
