General description

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 undergone electrical and mechanical testing which has shown that it is very flexible.
