Comparison of UV-curable and thermal silicone coatings for new linerless-label applications
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

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
