Abstract:
A method of producing a coated opaque article including a) applying from one or more inkjet heads a coating composition comprising at least 30 wt % of solvent to a surface of a transparent or opaque article to be coated; b) drying the coating composition for at least 30 seconds; and c) curing the coating composition to form a cured coating. The coating composition has a viscosity of from 5 to 50 cp at 25° C. and when the article to be coated is a transparent article, an opaque coating is applied to another surface of the article after step c), thereby rendering the coated article opaque.

A corresponding method of processing a work piece in such an arrangement indicates the steps to be used when processing a first and a second workpiece The ovens may have both a baking and a curing zone. A ventilation system with an air curtain (23) may be included.
Abstract:
A method of drying and/or curing an organic coating on a continuously running metal strip, includes heating the strip by electromagnetic induction in a tunnel furnace having an enclosure with hot internal walls and heating the enclosure. The heating of the strip by electromagnetic induction is coupled with heating by infrared radiation and heating by convection with a combustion gas. The heating of the enclosure of the furnace is performed by convection using the same combustion gas used for heating the strip by convection. A device for implementing the method is also provided.

Abstract:
A substrate coating method may include: translating the substrate in a first direction through a spray zone while spraying a fluid coating on a first uncoated surface portion to produce a first coated surface portion; heating at least the first coated surface portion to form a first cured coating while translating the substrate through the heating zone in the first direction and a second, opposite direction; manipulating a second uncoated surface portion in a position to be spray-coated; spraying the fluid coating onto the second uncoated surface portion while translating the substrate in the first direction through the spray zone to produce a second coated surface portion; and heating at least the second coated surface portion to form a second cured coating while translating the substrate in the first direction through the heating zone. The method may thereby provide the substrate with the first and second cured coatings.
