UV-A curing solutions, 365nm, 395nm and 405nm

Applications of UV-A 365nm, 395nm, and 405nm Solutions in Various Industries

UV-A radiation technology, with wavelengths of 365nm, 395nm, and 405nm, plays a crucial role in several industrial applications. By utilizing advanced LED technology, companies can enhance the efficiency of their processes, achieve higher radiation intensity, and take advantage of the strobe pulse function. The Manima Pollux driver is an essential device that enables this strobe pulse technology, designed to seamlessly integrate with existing industrial systems. This makes it possible to optimize the speed and precision of UV polymerization and other processes. Below are some key applications:
 

  1. Adhesives (Polymerization Adhesives)
    UV-A LED technology is often used to accelerate the curing of polymerization adhesives. The Manima Pollux driver ensures that strobe pulse technology is applied with high precision, activating the curing process at the exact moment needed. This technology allows adhesives to cure quickly and efficiently without heat development, making it ideal for applications in electronics, medical devices, and the automotive industry.
     

  2. Resins
    UV resins, which react to UV-A light at specific wavelengths, are effectively activated by LED technology. The Manima Pollux driver enables the use of strobe pulse technology, providing controlled curing of resins. In industries like 3D printing and other applications, this accelerates polymerization, leading to higher productivity and improved material properties. The driver allows for perfect synchronization of the UV-A light source with the process, offering greater precision without sacrificing quality.
     

  3. Coatings
    In the coatings industry, the combination of LED-UV technology and the Manima Pollux driver offers immense benefits. The strobe pulse function enables coatings to cure quickly and effectively without the drawbacks of overheating. This technology is particularly important for applications in the graphic arts, automotive, and construction sectors, where speed and reliability are critical. The driver integrates easily with existing systems, providing a flexible solution.
     

  4. Paints and Primers
    UV-sensitive paint and primer systems can be cured more quickly and efficiently using LED-UV radiation controlled by the Manima Pollux driver. The strobe pulse mode allows manufacturers to reduce drying time while maintaining the product's quality and finish. This makes the technology particularly valuable in the automotive and industrial finishing sectors, where rapid production is required.
     

  5. Glass Fiber Resin Composites
    UV-A LED technology accelerates the polymerization of glass fiber resin composites, which is essential for producing strong and lightweight structures. The Manima Pollux driver provides the strobe pulse functionality that further speeds up the curing process, making production more efficient without compromising the strength or durability of the material. This is particularly beneficial for applications in aerospace, automotive, and construction industries.
     

  6. Photocatalytic Reactor Systems
    In photocatalytic reactor systems, the Manima Pollux driver is used to apply strobe pulse technology, increasing the reaction rate of photocatalytic processes. This is critical for air and water purification applications, where photocatalytic reactions need to occur rapidly and efficiently. The strobe pulse functionality allows the UV-A light source to be precisely tuned to meet the process’s needs, resulting in higher efficiency and energy savings.
     

  7. Photocrosslinkable Hydrogels
    Hydrogels that react to UV-A light can be crosslinked quickly and precisely using strobe pulse technology. The Manima Pollux driver allows manufacturers to time the crosslinking process accurately, ensuring the mechanical properties and biocompatibility of hydrogels are optimal for applications in tissue regeneration and controlled drug delivery. This is especially useful in the medical sector, where precision and speed are paramount.


By combining UV-A light at 365nm, 395nm, and 405nm wavelengths with LED technology and the Manima Pollux driver, which enables strobe pulse functionality, companies can significantly benefit from improved production cycles, energy efficiency, and product quality. This driver allows precise control over the strobe pulse, resulting in a more flexible, energy-efficient production process that can be easily integrated into existing industrial systems.

 

 

Focusing LEDs compared to not focusing LEDs also has a lot of impact. Below is an image comparing our own LED fixtures, both without optics and with optics.

Strobing Techniques for UV-A LEDs

UV-A LEDs have the capability to strobe, a technique that enhances curing efficiency compared to continuous radiation. Strobing not only improves the effectiveness of the curing process but also helps extend the lifespan of the LEDs. This is because strobing generates less heat compared to continuous operation, preventing the thermal stress that could otherwise shorten LED life. In contrast, strobing with low/medium pressure UVC lamps can negatively affect their lifespan and is not a recommended approach, as it can be destructive to the lamp, which also requires warm-up and warm-down periods.
