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 a liquid vehicle. Since they are surface stabilized, UTDAu inks are highly soluble in nonpolar organic solvents and stable under atmospheric conditions at room temperature.

Silver nanoparticles have a 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 temperatures.

3   Inks can be prepared with different concentration upon request. Typical concentrations are given in the Table above.
Gold nanoinks are formulated in the same solvents or solvent mixtures as silver nanoinks.  Minimum curing temperature for gold nanoinks: 190-200 C.
All inks can be printed on glass. To improve adhesion to glass and other polar surfaces we provide an additive - adhesion promoter.

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 a liquid vehicle. Since they are surface stabilized, UTDAg inks are highly soluble in nonpolar organic solvents and stable under atmospheric conditions at room temperature.
