The Latest Happenings in Chemical Regulations in 2024
By Shannon L. Gainey, Ph.D., director of Global Regulatory Management, J.M. Huber Corporation The regulatory landscape for chemicals has become increasingly challenging. In particular, the sustainability benefits from UV/EB technologies (e.g. fast cure, low emissions, etc.) unfortunately are shadowed by the reproductive concerns associated with several photoinitiators and the … [Read more...] about The Latest Happenings in Chemical Regulations in 2024
UV-A Hard Coat for Polycarbonate Headlight Refinishing
By Michael J. Dvorchak, Dvorchak Enterprises, LLC The automotive industry over the last several decades has pushed the technology for automotive forward headlighting from glass to polycarbonate plastics (PC). Although there are obvious advantages to polycarbonate, such as weight reduction and improved safety, there also are issues with deterioration over time of the … [Read more...] about UV-A Hard Coat for Polycarbonate Headlight Refinishing
Characterizing Accuracy in Photopolymer AM: A Q&A with Michelle Hoffecker and Matthew Panzer from Carbon
Coordinated by Photopolymer Additive Manufacturing Alliance (PAMA)* Members Callie Higgins and Jason Kilgore, NIST Photopolymer additive manufacturing (PAM), or vat photopolymerization (VPP), is a powerful tool that enables three-dimensional (3D), micrometer-level control of the geometric, mechanical and chemical properties of a fabricated part. While useful and potentially … [Read more...] about Characterizing Accuracy in Photopolymer AM: A Q&A with Michelle Hoffecker and Matthew Panzer from Carbon
Formulating Urethane Acrylate Oligomers for Tough 3D-Printing Materials, Part 1
By Brian Dillman, IGM Resins The shift from rapid prototyping to durable good manufacture via 3D printing (3DP) steadily has increased the performance demands of the resins used in 3DP. Herein experimental data for the cured properties of formulations based on urethane acrylate oligomers is shown. Tensile mechanical properties, glass transition temperature and cure-induced … [Read more...] about Formulating Urethane Acrylate Oligomers for Tough 3D-Printing Materials, Part 1
