RadTech 2016 UV/EB Technology Conference and Exhibition

Attendance up, awards given in several categories

Radtech 2016’s Innovation Panel included Sharon Tracy, Steelcase; Alrick Warner, P&G; Christopher Seubert, Ford Motor Company; Todd Fayne, PepsiCo; Robin Wright, 3M; and moderator Lee Goldberg of Product Design and Development and Medical Design Technology magazines.

With attendance up five percent over the 2014 event, RadTech 2016 has been deemed a success. More than 80 exhibitors and 1,400 attendees gathered in Chicago for three days in May to discuss the latest innovations in the ultraviolet and electron beam industries, while also celebrating a number of award honorees.

Panels addressed food packaging, 3D printing, innovation

High-profile panels at RadTech 2016 brought together UV/EB users and suppliers to discuss the emerging impact of the technology in diverse applications.

The Food Packaging Panel contained a mix of industry experts in the formulator, regulatory and legal arenas, as well as a CPG company, Nestlé. While there were some light-hearted moments, Nestlé made a serious proposal that there should be complete transparency of all ink/coating/adhesive/press chemical raw materials to Nestlé via nondisclosure agreements. In addition, there were some somber moments as the panel discussed the prospect of intervention by governments of new laws regarding migration, the potential of over-regulation and the process of establishing uniform standards for food packaging print around the world. These are all tough problems and complex issues, but the first step to resolution is to get them on the table where knowledgeable experts can propose potential solutions.

The 3D Printing Panel discussed the latest advancements in 3D printing using UV technologies. Thought leaders in materials, equipment and end uses for UV technologies in 3D Printing participated, including Victor Latour, supervisor of digital design, Stoopid Buddy Stoodios; Sumeet Jain, director market development, Arkema Inc., Sartomer Business Unit; Lance Pickens, CEO and founder, MadeSolid; Mike Idacavage, vice president, business development, Colorado Photopolymer Solutions; Brian Adzima, materials scientist, 3D printing, Autodesk; and Alex Mejiritski, president, Spectra Group Limited.

Innovation awards

RadTech 2016 also recognized companies that use UV/EB technologies. At the RadTech 2016 awards dinner, several innovative, cutting-edge applications were celebrated.

Continuous Composites (CC3D)

CC3D has developed a new 3D printing process to print continuous fiber with UV-curable resin; they are reportedly the only company in the world 3D printing continuous fiber with thermoset epoxy and the only company to successfully print continuous fiber into free space. With a focus on functional composites additive manufacturing to scale, CC3D is providing an industrial solution to advanced manufacturing techniques of mid to large scale.


Seeking to lower its carbon footprint, Pepsico is looking to EB-flexo inks as a replacement for the use of solvent-based materials for snack food packaging. Technological developments around EB ink chemistry are creating stunning advances in print quality and aesthetics. Pepsico reports the use of EB technology reduces VOC emissions as much as 90%, with lower energy consumption when compared to conventional thermal drying. EB is considered “food friendly,” which enables Pepsi to make attractive, environmentally compliant packaging that is cost neutral when compared to incumbent solvent and thermal drying technologies.

Cleveland Steel Container

Cleveland Steel Container has developed the first commercial inline EB and UV process for rigid steel coil substrates in the manufacture of steel pails. CSC is the largest steel pail manufacturer in North America, with uses ranging from hazardous materials to cosmetics. CSC applies and cures EB and UV directly to steel coil for 5-gallon pail lids and bottoms. Beyond a dramatic reduction in energy requirements, CSC reports that since “EB coatings are 100% solids formulations, it means no loss of evaporated solvent from the applied coating. It also means less coating usage and required storage area compared to solvent systems.”


In a very innovative use of UV curing, Wavefront makes state of the art holographic films using advanced roll-to-roll continuous UV casting lines to manufacture nano/micro structure embossed films on a variety of film substrates. This capability allows WFT to manufacture micro-structures from 200 nanometers up to 150 microns. These unique structures can only be achieved using the latest UV curing and formulating technologies.

HRL Laboratories LLC

The HRL team demonstrated the first ever UV additive manufacturing of polymer-derived ceramics. By formulating pre-ceramic UV-curable polymers, the team at HRL demonstrated the first-ever additive manufacturing of fully dense, binder-less ceramics, published in the 1/2016 issue of Science. Potential applications for this novel technology include turbine engine components, hypersonic vehicle structures, MEMS devices and electronics packaging.

NOVAGARD Solutions

Novagard has developed the first industrial UV LED PSA installation on a coating line. Novagard converted a water-based PSA to a UV LED-curable PSA and now is using it to produce PVC foam rolls (more commonly known as weather stripping). The system consists of two 62″ wide banks of UV LED curing systems. Conventional UV lamps could not be used as they delivered too much heat to the substrate causing damage. UV LED was the only viable solution, allowing Novagard to pursue new market opportunities.

Carbon 3D

Carbon’s vision is “a future fabricated with light, where traceable, final-quality parts are produced at scale with CLIP technology.” CLIP – Continuous Liquid Interface Production – makes this possible by combining engineering-grade materials with exceptional resolution and surface finish. CLIP eliminates the shortcomings of conventional 3D printing by more rapidly producing objects. “From everyday products like tennis shoes and electronics to industrial components to highly customizable medical devices, CLIP makes it possible for creators to design the parts and products of the future.”

City of Cleveland

The City of Cleveland, including Cleveland’s Progressive Field ballpark, home of the Major League Cleveland Indians, was recognized for its exploration and use of UV-curable materials as a contribution to environmental sustainability in Cleveland. The city has found UV technology solutions to long-standing issues for protection against corrosion and to provide superior protection for metals, concrete, stones and other substrates in an efficient and fast curing manner.
