Profile: Solo Systems, Inc. designs and manufactures corona treater stations, corona treating components including electrode assemblies, corona treater rolls and epoxy corona treater roll coating. Corona treater stations treat plastic film to improve the adhesion of inks or glues for printing or laminating. It exposes the web material to the energy of an electrical corona discharge that changes the molecular structure of the web surface to more readily accept inks, adhesives and laminates. E-3 epoxy treater roll coating is the electrical insulation in the generating circuit of the conventional corona treater system. As high voltage is directed towards the coating, its electrical resistance causes ionization in the air and corona is formed & the web is treated.
