UV700-SR1J electrically conductive silver paste enables the formation of electronic circuits using only ultraviolet curing, without thermal curing. Forms a circuit that carries current by printing a circuit on base material with silver paste using screen printing technology, and exposing it to UV light for around 10 sec., instantly hardening the printed film even at room temperature. Is said to enable narrower width than in conventional screen printing, resulting in the creation of micro wiring with a width of 70 microns and electrical resistivity of 10^(-4) ohm-cm on surface-treated PET film.
