UV as the Energy Source for Industrial Processing of Coatings, Inks, and Adhesives

UV curing, the process of photoinitiated conversion of polymeric materials from a liquid to a solid, is a popular alternative to conventional drying. UV Curing is highly adaptable to a wide variety of coating applications, owing to some of its key attributes; it is (1) solventless, (2) low-temperature, (3) high speed, and (4) energyefficient. The physical properties of UV-cured materials are substantially affected by the lamp systems used to cure them. The development of the intended properties can depend on how well these lamp factors are designed and managed. Key exposure factors are (1) UV irradiance, (2) spectral distribution and (3) time.
