Incorporation of Carbon Nanotubes into UV-Polymerizable Formulations, Part 3
In the 3rd and 4th Quarter 2023 issues of UV+EB Technology, we discussed the preparation of nanocomposites made by incorporating carbon nanotubes (CNTs) into UV-polymerizable formulations. 1, 2 Those two articles summarized the experimental techniques developed by undergraduate students at the University of Houston-Downtown to determine how well single-walled carbon nanotubes … [Read more...] about Incorporation of Carbon Nanotubes into UV-Polymerizable Formulations, Part 3
Colorblind EB
Colorblindness has long been touted as an advantage of electron beam and a key differentiator between EB and UV technologies. And it’s true, the penetration of UV light is dependent on the optical clarity of the material it’s interacting with, while EB penetration is governed by material density (and chemical composition) – i.e., zip, zero, nada to do with color, opacity or any … [Read more...] about Colorblind EB
Sneak Peek at the First-Ever ASTM Vat Photopolymerization Design Guide
By Callie Higgins, NIST With the rapid advancement and adoption of vat photopolymerization (VPP) as an additive manufacturing (AM) technology, it naturally follows that discussions regarding the need for standards on how to safely and effectively implement VPP are increasing in frequency. In answer to this need, a team of VPP experts ranging from resin formulators and OEMs … [Read more...] about Sneak Peek at the First-Ever ASTM Vat Photopolymerization Design Guide
Cationic Curing Can Be a Sustainable Solution for Challenging Applications
By Vanessa Maurin, David Engberg, Stefan Lundmark, Pia Wennerberg and Martin Olofsson, Perstorp AB, and Guillaume Bano, Céline Croutxé-Barghorn and Xavier Allonas, Laboratory of Macromolecular Photochemistry and Engineering Cationic UV curing brings clear benefits, such as low shrinkage and excellent adhesion, to difficult substrates like as plastic, metal and glass.
