Application:	Screen-printable silver paste material for semitransparent and flexible metal–semiconductor–metal photodetectors with liquid-phase procedure: This study presents a flexible MSM photodetector using conductive Ag paste electrodes made through a screen-printing liquid-phase process, offering insights into the semitransparency of Ag paste solutions (Tsai et al., 2022 ). Effect of polymer binder on the transparent conducting electrodes on stretchable film fabricated by screen printing of silver paste: This research examines the role of polymer binders in silver pastes used on flexible polyurethane and polyester films, focusing on rheological properties (Lim et al., 2017 ). Deposition of high conductivity low silver content materials by screen printing: Investigates novel polymer inks alongside traditional paste materials for their application in both rigid and flexible circuit printing, emphasizing cost-effectiveness and performance (Jewell et al., 2015 ). Printability of the screen-printed strain sensor with carbon black/silver paste for sensitive wearable electronics: Explores the use of carbon black/Ag nanocomposites in pastes for flexible printed electronic products, enhancing the sensitivity and flexibility of these devices (Qi et al., 2020 ). High-concentration copper nanoparticles synthesis process for screen-printing conductive paste on flexible substrate: While focusing on copper, this study provides relevant comparisons to silver pastes, detailing formulations suitable for screen-printing on flexible polyester substrates (Tam and Ng, 2015 ).

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.
