LED UV Curing in an Industrial World
LED UV light has moved into the mainstream in industrial manufacturing as the preferred process to instantaneously cure UV-light-reactive adhesives, coatings and finishes for superior bonding, sealing, coating and finishing on substrates of all kinds.

Its use is widespread in the automotive, medical device, electronics and consumer goods industries to name a few, in products of all kinds, ensuring perfect curing, even at top production speeds, as they roll off the assembly line.
Industrial Benefits
A big advantage to using LED UV versus conventional UV is the elimination of IR heat output during the curing process. This expands its application to a wide range of heat-sensitive materials in the industrial space, such as the seal on the top of a syringe and an LED screen. Additionally, the energy can be directed precisely where it is needed, without damaging other sensitive components.
LED UV’s ability to cure within seconds speeds production while ensuring optimal adhesion and bonding and a more uniform and durable finish that stands up to the rigors of the most demanding industrial environments.
Another benefit is that UV LED systems offer the smallest form factor for easy integration into existing marking, decorating and coating machines. They eliminate the need for bulky cooling systems that are required with traditional UV to maintain bulb temperature. LED UV also the most energy-efficient curing process and provides considerably longer bulb life than conventional systems.
Another growing use for LED UV treatment is to provide a safe, efficient way to disinfect water on a large scale without the need to use of harmful chemicals.
The UV-C spectrum has become especially relevant and in demand to combat the spread of the COVID epidemic. It’s used to sterilize air especially in public spaces like hospitals, schools, airports and anywhere else people congregate on a large scale with limited ventilation and to disinfect surfaces.
