    Abstract: The invention relates to a process for the production of strongly adherent coatings on an inorganic or organic metalized substrate, 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 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.

    Abstract: A method and system for improving the capability of a surface of an organic structure to bond with another material includes irradiating a target area of the surface of a structure with pulsed, incoherent optical energy having wavelength components which range from 160-5000 nanometers at an intensity sufficient to photodecompose any adventitious organic substances on the surface and to photodecompose a thin layer of molecular bonds forming the surface of the structure; and exposing the target area of the surface to ionized gas that chemically reacts with the target area of the surface to increase the surface free energy of the surface. A similar method and system may also be employed to improve the bondability of a metallic surface by first precleaning the metallic surface to dislodge any inorganic substances from the surface; and second irradiating a target area of the surface with pulsed, incoherent optical energy having wavelength components in the range of 160-5000 nanometers at an intensity sufficient to photodecompose any organic substances present on the surface.
