| Résumé : |
Aficionados of 1960s music will likely recall the 1967 Sonny and Cher classic The Beat Goes On, a catchy commentary on the world's constant, unrelenting progression forward and that no matter how drastically some things change, other things will perpetually remain the same.
PPCJ readers may agree that this same, timeless observation remains truc within the coatings, inks and adhesives industries as well. Even as processes and technologies continue to evolve and improve, several bottom-line business tenets remain constant. Just as in the days of old, businesses today continue to innovate the development of attractive, high quality products that are manufactured efficiently and safety, and are both attractively priced to the buyer and provide a decent margin to the business.
So what does this have to do with electron beam (EB) technology ? As it turns out, plenty. Long regarded as a highly specialised option for curing and crosslinking inks, coatings and adhesives, EB technology continues to earn the reputation of being both powerful and cost effective.
Though it is a technology that has existed for more than 40 years, many seasoned coatings professionals are still not aware of EB curing as an alternative to oven drying (or ultraviolet (UV) curing). Initially intrigued by EB's ability to cure surfaces by altering molecular structures instead of thermally evaporating solvents or water (or in the case of UV curing, instead of using light-activated photoinitiators to initiate curing), these professionals become even more interested in EB once they appreciate that this technology can make their printed surfaces more abrasion resistant, more attractive and - often most importantly - can provide substantial cost savings to their company. |
