WHAT IS UV LED CURING ?

Click:[1517] Publish Time:2018-01-31

“Ultraviolet (UV) light is an electromagnetic radiation with a wavelength from 400 nm to 100 nm, shorter than that of visible light but longer than X-rays.” (Source: Wikipedia). Ultraviolet or UV curing is used to create a photochemical reaction using high intensity Ultraviolet (UV) energy or “light” to quickly dry inks, adhesives or conformal coatings. Most materials cure with a UV wavelength around 350 ~ 400nm although some materials require UVC energy near 255nm. Light Emitting Diodes (LED's) come in various "colors" including Ultraviolet (UV). Unlike traditional UV emitters, LEDs have very focused UV Wavelengths which can be tailored to the application. Because of the typical wavelength used for UV curing LEDs with an output wavelength of 365nm or 385nm are commonly used for curing applications.
