By Carlo Trentalange, application chemist, Radlab AG Direct adhesion of acrylate-based UV coatings to metal surfaces traditionally has posed challenges due to the intrinsic kinetics of radical photopolymerization chemistry. Nonetheless, interest in UV technology for metal applications has grown significantly in recent years, primarily driven by the benefits of lower energy … [Read more...] about Improving Direct-to-Metal Adhesion of UV-Curable Coatings
Photopolymer Additive Applications in AI Data Centers
The UV additive manufacturing techniques discussed in prior columns have focused primarily on hardware approaches to additive manufacturing or the chemistry developed in combination with those approaches. 1 The current column is a brief survey of the use of UV additive manufacturing to enable and enhance the capabilities of artificial intelligence (AI). The subject of this … [Read more...] about Photopolymer Additive Applications in AI Data Centers
UV-C Is Much More Than 10 Nanometers: Why the UV-C Band Demands Measurement
By Darrin Leonhardt, chief innovation officer and head of engineering, EIT 2.0 A UV curing line runs flawlessly for two years. Then the lamp supplier changes. The replacement units are the same wattage, the same lamp type, the same rated output. The radiometer reads within 2% of the original baseline. Three days into production, cure failures begin appearing downstream – … [Read more...] about UV-C Is Much More Than 10 Nanometers: Why the UV-C Band Demands Measurement
Novel Self-Curing Resin with Glyoxylate Technology: A Formulation Tool for LED-Curable Coatings and Inks
By Paolo Betti, synthesis manager, IGM Resins Self-curing resins represent a significant advancement in the field of polymeric materials in UV technology. Due to the increasing regulatory concerns linked to certain classes of low-molecular-weight photoinitiators, the development of formulations based on resins with built-in initiation capability has become an attractive … [Read more...] about Novel Self-Curing Resin with Glyoxylate Technology: A Formulation Tool for LED-Curable Coatings and Inks
ABCs of UV Measurement & Process Control: Letter A
I was “volunteered” for this UV+EB Technology column journey in 2019. This column (number 30) is close to the same number of years I have been involved with UV technology. I still learn every day and get excited about new applications, while not forgetting the basic building blocks of UV, measurement and process control. This column will focus on the “ABCs” of UV measurement … [Read more...] about ABCs of UV Measurement & Process Control: Letter A
