Top Five UV+EB Technology Articles from 2017
With three full years of UV+EB Technology magazine under our belt and work on the first issue of 2018 well underway, we paused to see the topics with which our readers spent the most time in 2017. The following stories were the top reads for more than 29,000 visitors to the website.
- Photoinitiator Selection for LED-Cured Coatings
LED sources are rapidly gaining in popularity in the UV-cured coatings market as they offer reduced cost, longer life and environmentally-friendly alternatives to conventional lamps. Transitioning to UV LED, however, often requires more than just a simple equipment change.
- Floor Coatings with UV LED Curing: A Focus on Performance and Properties
Floor coating compositions were prepared from monofunctional, difunctional and trifunctional acrylates, as well as urethane acrylates (UA), and used to determine the effect of double-bond equivalent weight (DBEW) mercapto-based resin, high-viscosity UA and LED photoinitiators on final cured film properties when cured under an atmosphere of air vs. nitrogen.
- UV-Curable High Refractive Index Monomers and Oligomers for Optical Films
Recent technological trends in thin film transistor-liquid crystal displays (TFT-LCDs) include thinning, lightening, decreasing power consumption and decreasing costs. In particular, low power-consuming products are in high demand worldwide because of increased energy-saving awareness.
- Cationic Curing of Automotive Coatings
Automotive paint shops are typically among those using the most energy-intensive processes in a manufacturing plant. Studies by Argonne National Lab (ANL/ESD/10-6), Michigan Technological University (Automobile Assembly Painting: Energy and Environmental Impacts [John Sutherland]) and others estimate that 50 to 75 percent of the energy consumption and carbon dioxide emissions from material transformations for an assembly plant are directly related to paint, particularly for the painting, HVAC and heating.
- Q&A: Which is more important irradiance or exposure?
Irradiance and exposure are both important, but the relative effectiveness depends on the physical chemistry of an ink, coating, adhesive or paint as well as on the optical thickness of the UV-curable material and the properties required of the end application.
