In electrical engineering acorona discharge<\/strong> is a discharge that occurs on high-voltage conductors. A similar discharge pattern results when a high-voltage electrode (several kVs) is brought into close proximity with the substrate\u2019s surface to be treated. An earthed counter electrode is in contact with the back of the substrate.<\/p>\n

As early as more than fifty years ago it was recognised that the targeted application of such a discharge can be used to improve adhesion on plastic surfaces<\/strong> and other substrates. A discharge zone is formed in the gap between the electrodes. This zone has a high concentration of different activated atoms and molecules striking the substrate surfaces to be treated.<\/p>\n

The closed molecule chains of the surface are cracked open, allowing activated species, primarily oxygen radicals, to be deposited. Polar molecules <\/strong>are then generated on the previously non-polar surface, and colour molecules can chemically bind to them. Corona treatment is a method using physical surface activation.<\/p>\n\r\n <\/div>\r\n <\/div> \r\n <\/div> \r\n \r\n <\/div> \r\n <\/section>\n\n\n

We exclusively produce semiconductor generators with a significantly higher degree of efficiency<\/strong> and less stray radiation than tube-based models. The high-frequency clocking of the applied high voltage ensures the development of continuous plasma<\/strong> for reliably clean results at a consistently high level.<\/p>\n\r\n <\/div>\r\n <\/div> \r\n <\/div> \r\n \r\n <\/div> \r\n <\/section>\n\n

Can you restrict the surface treatment to specific areas?<\/h3>\r\n
<\/div>\r\n <\/div>\r\n \r\n
\r\n \r\n
\r\n

Selection and well-arranged layout of the right electrodes can restrict activation to specific areas. Our customised stations<\/a> enable precise surface treatment,<\/strong> ensuring good adhesion and reliably replicable results.<\/p>\n

Does corona treatment require a vacuum chamber?<\/h3>\r\n
<\/div>\r\n <\/div>\r\n \r\n
\r\n \r\n
\r\n

No. All our corona systems operate at atmospheric pressure. This means that the plasma needed for activation is created in regular ambient air, allowing you to integrate surface activation with your regular production process<\/strong>. Thanks to a higher treatment speed there is no negative impact from surface treatment on your manufacturing productivity.<\/p>\n
