e|5 Showcases Cutting Edge UV and EB Technology

There are very few places where one might find industry leaders from companies and institutions as diverse as the U.S. Air Force, Ford Motor Company, P&G, Boeing Phantom Works, Motorola and Armstrong Floor Products.

One area they do have in common is that they have an interest in ultraviolet (UV) and/or electron beam (EB) curing. For these companies and so many others, e|5: UV & EB Technology Conference & Expo, the world's largest UV & EB event, presented by RadTech International and held at McCormick Place in Chicago, IL, April 24-26,� showcased the possibilities of using UV and EB technology.

The rapid growth of UV and EB was clearly illustrated by the record number of attendees, most notably end-users, who came to the show. By the end of the first day, e|5 already reached the attendance figures from the 2004 showcase in Charlotte, NC.� RadTech International leaders were delighted with the show.

"I'm very happy with e|5," said Gary Cohen, executive director of RadTech International NA. "Our pre-registrations are at a record number, and the number of end-users is up dramatically. In terms of attendance, after the first day we are already ahead of our total attendance at Charlotte in 2004. What is particularly interesting is that end-users are signing up for our conferences, which shows that they are very interested in how they can use energy-curing technologies." �� �

Sartomer's booth was active throughout e|5.

"With rising energy costs, increasing international competition, and continuing environmental concerns, manufacturers are increasingly looking to UV and EB technology to address these challenges," said David Harbourne, RadTech president, and president of Fusion UV.�"Our event highlighted this technology's tremendous enabling versatility, with a broad cross-section of manufacturers in attendance including firms engaged in the production of motor vehicles, food packaging, ink jet products, aerospace and defense, wood, metals, plastics and electronics."

"The aim of our event is to educate manufacturers about the operational benefits of UV and EB," said Mickey Fortune, director of e|5.�"At this event we recorded our highest number ever of UV/EB users and potential users seeking to learn the latest on the technology, with overall attendance at a record level reaching over 2,700."

"Our objective at RadTech is to get more end-users to our conference," said Paul Elias, business director, specialty products for Sartomer. "We have the right story to tell. That's how we hope to grow it. UV and EB curing can save money and drive more business. These are two big keys."

Conferences and Presentations

Among the highlights at e|5 were eight conferences for end users, featuring speakers from the companies mentioned above among many others. The technical conference featured 27 individual sessions while the exhibition itself was comprised of 120 companies and more than 90,000 square feet of displays.

End-user sessions on the first day covered areas as diverse as UV Wood Finishing Applications & Focus on UV for Cabinetry; Developments in UV Curing for Automotive OEM, Tier One & Refinish Applications; UV & EB Technology for Aerospace, Defense & Homeland Security Applications; and Advancements in UV Curing for Flexible Electronics.
