Regulations on volatile organic compound (VOC) emission have caused solventborne pressure-sensitive adhesives (PSAs) to be gradually replaced by hot-melt or waterborne PSAs.
UV spot-curing systems have been used in assembly and manufacturing processes for over 30 years. Historically, mercury arc lamps have been used as the curing source in a range of industrial applications and processes to polymerize adhesives. With their broad spectrum and high output, lamps have provided an effective solution for many years.
