By Nancy Cates, contributing writer, UV+EB Technology A focus on ensuring customer satisfaction, as well as eliminating handling and excessive line maintenance, led the management at Microplastics, Inc., St. Charles, Illinois, to move to UV cure about a dozen years ago. "We started using UV applications around 2005," said Jim Krause, vice president for engineering. Prior … [Read more...] about Microplastics Works with Clients to Achieve Satisfaction Using UV Cure

Q&A: Are there different ways to use radiachromic films?
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?
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
Three-Dimensional and Uniform UV Curing Using Integrating Sphere Technology
By Thomas Efsen, managing director, Efsen UV & EB Technology An integrating sphere uses multiple diffuse reflections of light incident on the sphere inner surface to homogenize the light over the entire surface (Figure 1). This results in uniform irradiance at all points on the interior surfaces of the integrating sphere. This has been applied to UV curing by … [Read more...] about Three-Dimensional and Uniform UV Curing Using Integrating Sphere Technology
