How Fast is UV LED Curing? Unlocking Rapid Industrial Speed
How Fast is UV LED Curing? How fast is UV LED curing? The cure time for inks, coatings, and adhesives can take milliseconds to a couple of seconds with the ultrafast, effective process of UV LED curing. Unlike traditional mercury lamps that use UV technologies, UV LED systems provide full-spectrum UV (typically 365-405 nm) light, and the photoinitiators in the formulation get activated immediately. Some of the cure time factors are: • If more irradiance is used, the time taken decreases, and curing speed is heavily reliant on intensity. For example, a UV LED output of 8-16 W/cm² can cure so a lot of inks can cure in under 1 second. • More opaque or thicker materials pose a need for more energy to fully polymerize. Take 600-800 mJ/cm² for example. • Material features like the thickness and type of ink photoinitiator, along with adhesive and coating, determine the speed of cure. • At a proper system configuration, conveyor speeds can be set to 50-150m per min with LED systems. UV LED curing has accelerated systems for the production of medical devices, electronics, and printing because of reduced heating and improved speed and durability. The average faster print time UV ...
