By R.W. Stowe, UV applications engineering consultant, Heraeus Noblelight America LLC Since discussing the use of radiachromic films in UV+EB Technology,1 we have received a few questions on various methods of using them. There are essentially two types of radiachromic films, but the easiest to use are films or tabs whose surface is coated with a photochromic coating. … [Read more...] about Q&A: Are there different ways to use radiachromic films?
An Environmental Approach to UV/EB Resin Disposal
By Nick Talken, senior chemist, Molecule Corp., and Paul Snowwhite, CEO, Applied Molecules Background Ultraviolet- and electron beam-curable resins are rapidly becoming more commonplace in many existing and emerging industries. When exposed to UV or EB, these resins undergo rapid polymerization, from liquid to solid in seconds or milliseconds. Traditionally, UV/EB materials … [Read more...] about An Environmental Approach to UV/EB Resin Disposal

Ink Migration and Food Safety Take Center Stage at Inaugural RadTech Packaging Conference
By Richard Romano, What They Think One of the hottest topics these days is packaging, and to take an in-depth look at the technical requirements of packaging, RadTech International North America (RadTech) held its inaugural UV+EB Packaging Conference on October 24 in Philadelphia. Attracting a broad mix of packaging printers and converters, would-be converters, and brand … [Read more...] about Ink Migration and Food Safety Take Center Stage at Inaugural RadTech Packaging Conference
Non-Reciprocity of Exposure of UV-Curable Materials and the Implications for System Design
By R. W. Stowe, UV applications engineering consultant, Heraeus Noblelight America LLC Abstract Using exposure data of various (mostly commercial) coatings, inks and paints, this study demonstrates that differences in irradiance profile will result in different material behavior (properties) and, consequently, exposure requirements. Using various quantifiable performance … [Read more...] about Non-Reciprocity of Exposure of UV-Curable Materials and the Implications for System Design
