LAGOA SANTA, MINAS GERAIS, Brazil - Tuesday, November 12th 2013

Nanum Nanotecnologia S.A., a Brazilian Company, is pleased to announce that it is supplying functionalized, water-based high concentrated magnetic dispersion to HP for the security magnetic inkjet ink MICR.

Nanum was chosen by HP for its ability to develop, scale and produce nanomaterials with the highest control standards. It has showcased the possibility of using nanotechnology on existing industrial applications, overcoming the initial cost barriers and providing customized products and solutions to its clients.

The product is a very high concentrated ferrofluid with a high stability and with the average particle size of about 50 nanometers. This ferromagnetic fluid is used in thermal inkjet systems to print financial documents using the MICR technology.

Since the magnetic particles are solids and insoluble in water, they need to be very small to avoid the cartridge┬┤s nozzles to clog, but on the other hand, a high concentration of these small solid particles must to be present to guarantee a good magnetic signal response. This is where Nanum provides innovative solutions through proprietary processes, that allows a bond of other chemicals and additives to the nanoparticles, creating very stable water base dispersion with up to 50% of solids.
