It is important to consider the variables associated with the LED source and proper measurement tools in order to understand, maintain, and control the adhesive curing process.
UV LEDs with peak spectral outputs of 365, 385, 395, or 405 nanometers (nm) are increasingly being used to cure adhesives formulated to work with LEDs. The impact of spectral differences should be evaluated based on the adhesive, photoinitiator package, and desired cure properties.
