Inks and coatings

Conductive inks

Henkel Acheson inks can be used to create circuit substrates on polyester foil using polymer thick film technology. In addition to long-established materials, the portfolio also includes materials with a lower silver content, as well as conductive but transparent materials based on silver nanowires. If we want to install high-performance devices, the right solution is a varnish that hardens at a higher temperature, with the conductive particles sintered during curing, thus ensuring outstanding thermal and electrical conductivity. If the substrate is exposed to bending, even after curing, Henkel’s flexible inks provide a suitable solution.

Insulating inks

When manufacturing circuits, two wires may cross. In such cases, Henkel’s UV light-curing dielectric coatings are the solution. Curing with UV light is beneficial, as repeated heat treatment does not harm the foil, which in a given case could cause its deformation.
