UTDAg Conductive Silver Nanoinks
UTDAg silver nanoink is general-use ink for aerosol or ink-jet printing on variety of substrates. UTDAg is based on silver nanoparticles with average size around 10 nm and dispersed in liquid vehicle. Since it is surface stabilized, UTDAg inks are highly soluble in nonpolar organic solvent and stable under atmospheric conditions at room temperature.
Key Ink Properties

~ 7 - 10 nm |
Silver concentration |
~ 10-50% |
Solvent |
Hydrocarbon |
Viscosity, can be controlled |
1 - 10 cP |
Shelf life |
>3 months at room temperature |
Silver nanoparticles have low sintering temperature and can be used on inexpensive substrates, such as paper, polyester, polyimide and others. The resistivity of UTDAg ink decreases with time at required temperature.

UTDAu Conductive Gold Nanoinks
UTDAu gold nanoink is general-use ink for aerosol or ink-jet printing on variety of substrates. UTDAu is based on gold nanoparticles with average size around 4 nm and dispersed in liquid vehicle. Since it is surface stabilized, UTDAu inks are highly soluble in nonpolar organic solvent and stable under atmospheric conditions at room temperature.
Gold nanoparticles have low sintering temperature and can be printed on ITO and glass substrates. The resistivity of UTDAu40 ink decreases with time at required temperature.
