| abstract |
A process and the corresponding apparatus for the production of strongly adherent coatings on an inorganic or organic substrate is disclosed, wherein in a first step: (a) a low-temperature plasma, a corona discharge or a flame is caused to act on the inorganic or organic substrate; in a second step: (b) one or more photoinitiators or mixtures of photoinitiators with monomers, containing at least one ethylenically unsaturated group, or solutions, suspensions or emulsions of the afore-mentioned substances, are applied at normal pressure to the inorganic or organic substrate; in a third step: (c) using suitable methods those afore-mentioned substances are dried and/or irradiated with electromagnetic waves; and, optionally, in a fourth step: (d) the substrate so pretreated is provided with a coating and the coating is cured or dried. |
