What is Corona Treating?

Corona surface treatment is a variation of plasma surface treatment. While plasma surface treatment is more concentrated, corona surface preparation functions as an ionized cloud and is able to treat larger areas at the expense of focused energy. The corona treatment chemically reacts with the bonds of the treated material to raise surface energy and increase adhesion ability. The corona surface treatment of these materials allows for a higher bond capacity of inks, paints, adhesives, and surface coatings.
