Abstract: A process includes vacuum coating a shaped profile with a UV curable coating composition and subsequently curing the coated shaped profile to form a shaped profile having a uniform coated, cured coating. The curing is carried out with a pulsed UV device operated at a pulse frequency at pulse power such that the coating composition is uniformly cured over the coated surfaces of the shaped profile. The process is carried out continuously to coat and cure a shaped profile moving lengthwise through sequentially arranged coating and curing devices. An apparatus for carrying out the process that includes a vacuum coater and a UV curing chamber.

Abstract: A process and apparatus for curing UV-curable coatings present on a wood substrate. The process and the apparatus include the use of pulsed UV lamps to expose a substrate to curing UV light under conditions that do not substantially raise the temperature of the substrate undergoing curing.
