Title (EN) METHOD AND APPARATUS FOR PROVIDING LOW GLOSS AND GLOSS CONTROLLED RADIATION-CURED COATINGS
(FR) PROCEDE ET APPAREIL DE FORMATION DE REVETEMENTS POLYMERISES PAR RADIATION AYANT UN LEGER LUSTRE ET UN LUSTRE CONTROLE
Abstract: front page image
(EN)A method and apparatus for providing low gloss and controlled gloss radiation cured coatings, and for effecting on-line control of the degree of gloss provided. A radiation-curable coating of a composition which includes inert particulates is first irradiated with curing radiation of wavelengths to which the coating is responsive but having substantially no distribution beneath about 300-nm (5), and is subsequently irradiated with curing radiation of wavelengths to which the coating is responsive including substantial radiation at wavelengths beneath 300nm (6). Gloss control is obtained by adjusting the spectral distribution, the intensity, or the dose of the initial radiation, or by adjusting the time interval between the initial and subsequent irradiation steps (8).
(FR)Procede et appareil de formation de revetements polymerises par radiation ayant un leger lustre et un lustre controle, et de controle directe du degre de lustrage. Un revetement polymerisable par radiation d'une composition qui comprend des particules inertes est premierement irradie avec une radiation de longueurs d'ondes de polymerisation auxquelles le revetement est sensible mais n'ayant sensiblement aucune distribution en dessous de 300 nm environ (5), puis il est irradie avec une radiation de longueurs d'ondes de polymerisation auxquelles le revetement est sensible, comprenant une radiation a des longueurs d'ondes en dessous de 300 nm (6). Le controle du lustrage est obtenue en reglant la distribution spectrale, l'intensite, ou la dose de radiations initiale, ou en reglant l'intervalle de temps entre les etapes (8) d'irradiation initiale et ulterieure.
