Nano-metal Ink
Electro-conductive Ink
for Fine Patterning,
”Au”Series
NANOMETAL INKs are produced by the Gas Evaporation Method. These newly developed inks consist of metal nanoparticles dispersed stably and not aggregated in some organic solvent. The inks enable to form electro-conductive fine patterns directly by printing processes such as ink-jet printing.
Au NANOMETAL INK enables to form Au films at the curing temperature of 250℃.
