Products

Across all applications our silver nanoparticle formulations provide the following: 

• Superior conductivity (as low as 2 x bulk silver)
• Lower temperature processing/curing (as low as 80°C)
• Very short cure times (as little as 0.5 sec with conventional heaters)
• Aqueous solvent system for lower toxicity

Commercial Formulations:

Aqueous silver nanoparticle particle dispersions:

SP-100 (Base silver nanoparticle dispersion)
Silver nanoparticles dispersed in an aqueous surfactant solution.  This base is used in all of our formulated conductive printing inks.  The material can be used as an additive in flake based conductive inks, a sintering aid for silver or copper circuits, and other non-electronics applications.  Once heated to cure this material will form cohesive silver films, but will not adhere to most untreated and uncoated substrates.  This material is available at concentrations from 1-60 weight % silver.

Formulated silver nanoparticle inks for printed electronics:

PFI-200 (Flexographic printing ink)
Silver nanoparticles formulated with rheology modifiers and humectants to allow for improved processability in flexographic printing applications.  Once heat treated this material will form highly conductive and cohesive silver films, but will not adhere to most untreated and uncoated substrates.  This material is typically used on treated and coated substrates or when the material will be over coated with other graphic arts inks and coatings. Typical silver concentration in this ink is from 38-45 weight % silver.

PFI-201 (Flexographic printing ink)       
Flexographic formulation that contains our silver nanoparticles formulated with rheology modifiers and humectants to allow for improved processability as well as binders which provide adhesion to most untreated.  Once heat treated this material will form highly conductive and cohesive silver films, and will adhere to most untreated and uncoated substrates.  Typical silver concentration in this ink is from 38-45 weight % silver.

PGI-100 (Gravure/Intaglio printing ink)
Silver nanoparticles formulated with rheology modifiers and humectants to allow for improved processability in gravure printing applications.  Once heat treated this material will form highly conductive and cohesive silver films, but will not adhere to most untreated and uncoated substrates.  This material is typically used on treated and coated substrates or when the material will be over coated with other graphic arts inks and coatings. Typical silver concentration in this ink is from 40-50 weight % silver.

PGI-101 (Gravure printing ink)       
Gravure formulation that contains our silver nanoparticles formulated with rheology modifiers and humectants to allow for improved processability as well as binders which provide adhesion to most untreated.  Once heat treated this material will form highly conductive and cohesive silver films, and will adhere to most untreated and uncoated substrates.  Typical silver concentration in this ink is from 40-50 weight % silver.

Developmental Formulations:

POI-100 (Letterpress/Dry Offset/Lithographic ink)
Developmental high viscosity formulation that has been printed by letterpress, dry offset, and lithographically.

PSI-100 (Silk Screen Ink)
Higher viscosity formulation being developed as an aqueous screen printable ink.

PIJ-100 (Inkjet ink)
