By Tim Rummel, technical mgr.-North and Central America, Wacker Chemical Corp. Linerless labels provide unusual challenges for silicone release coatings, as the thermal-imaging paper contains unique chemistries and is very temperature-sensitive. For this reason, the majority of linerless labels are made with UV-curable silicone. While UV-curable silicones have some clear … [Read more...] about Comparison of UV-curable and thermal silicone coatings for new linerless-label applications

How structured release liners improve performance for high-end tape, label and other applications
By Dr. Tobias Nienke, technical account mgr.-Pressure-Sensitive Applications, Mondi Functional Paper & Films Structured release liners combine air egress, slideability and repositionability to enable easier installation of pressure-sensitive products, such as tapes, graphics and labels. A canal structure is applied to the surface of the liner during the extrusion … [Read more...] about How structured release liners improve performance for high-end tape, label and other applications
UV-LED measurement solutions for adhesive-curing applications
By Jim Raymont, director of sales, EIT 2.0 LLC UV LEDs with peak spectral outputs between 365-405 nanometers (nm) increasingly are being used to cure adhesives, but converting a process from mercury to LED may involve more than “turning on” an LED and “turning off” a mercury source. It is important to work with your supplier/formulator to test, evaluate and – if needed – … [Read more...] about UV-LED measurement solutions for adhesive-curing applications
Toward a better understanding of the regimes of slot-die coating
By E. J. (Ted) Lightfoot, Ph.D., principal, Ted Lightfoot LLC Introduction Slot-die coating currently is the most widely discussed coating method. This is partially due to the large body of scientific knowledge on slot-die and partly due to its use in manufacturing advanced-materials applications, such as batteries and fuel cells, as well as academic investigations of … [Read more...] about Toward a better understanding of the regimes of slot-die coating
