SunChemical Gwent C2081126P2 Conductive Silver Polymer Paste
Categories:	Fluid; Metal; Other Engineering Material; Ceramic/Metallic Coating
Material Notes:	This product is a thermoplastic screen printing ink, developed for use in membrane touch switch applications as well as counter electrode in electrochemical sensors and conductive tracks. It may be screen printed on to flexible polymeric substrates, such as Polyimide, PEN and PET substrates, to create a highly conductive track for general circuitry. The ink has under gone electrical and mechanical testing which has shown that it is very flexible. Screen Printing Equipment: semi-automatic, manual Screen Types: stainless steel, polyester, mesh 156-325tpi Substrate: Polyimide, PET, PEN Information provided by Gwent Electronic Materials Ltd.
