摘要

UV curing, the process of photoinitiated conversion of polymeric materials from a liquid to a solid, is a popular alternative to conventional drying. The number and variety of applications for UV-curable inks, coatings, and adhesives continue to expand at a rapid pace and pose new design challenges to increase cure efficiency, speed, and the physical properties of the cured polymer film. UV curing is highly adaptable to painting, printing, coating, decorating, and assembling of a great variety of products owing to some of its key attributes. It is a solventless process―cure is by polymerization rather than by evaporation, so VOC emissions are eliminated; a low-temperature process―heat is not required; a high-speed process―cure is nearly instantaneous; an energy-efficient process―energy is invested only in the curing reaction, not in heating; and easily controlled―inks and coatings do not "dry," so do not set up in printing/coating or dispensing equipment.
