The Key to Perfect Surface and Deep Curing with UVA and UVC LED: Enhancing Process Efficiency and Quality
The curing of coatings industry continues to evolve, and businesses consistently seek technologies that enhance efficiency, durability, and overall product quality. Among the latest innovations, UVC curing has emerged as a game-changer. At EASYTEC, we are at the forefront of this technological shift, combining UVC and UVA curing to provide unmatched surface and deep-layer curing results.
In addition to its ability to improve curing efficiency, UVC LED technology also opens the door to curing conventional coatings with UV LED under specific conditions. This expands the range of materials that can benefit from energy-efficient UV curing.
In this blog, we’ll dive into UVC curing, its benefits, and why combining it with UVA is the perfect recipe for success.
What is UVC Curing?
UVC curing uses ultraviolet light in the 100–280 nm wavelength range to rapidly cure coatings, inks, and adhesives. This technology works by initiating a photochemical reaction in materials containing photoinitiators, leading to polymerization and hardening. The primary strength of UVC light lies in its ability to cure the uppermost layer of a coating with unparalleled precision.
This surface-level curing is critical for achieving properties like high gloss, scratch resistance, and durability, especially in industries like automotive, electronics, and furniture manufacturing.
Additionally, one of the key advantages of UVC LED technology is its ability to enhance the curing of conventional coatings, which are traditionally designed for mercury-based UV lamps. Under certain conditions, UVC LEDs can activate photoinitiators in conventional formulations, making it possible to transition to energy-efficient LED-based curing.
UVC and UVA: A Perfect Pair
While UVC curing excels at surface curing, UVA curing (320–400 nm) penetrates deeper into the material. By combining these technologies, manufacturers can achieve both surface hardness and deep-layer polymerization in one seamless process.
Depth of Curing: A Technical Perspective
UVA Curing: UVA light penetrates up to 2-3 mm, making it ideal for curing the internal structure of thicker coatings. This ensures structural integrity and eliminates the risk of under-cured areas, which could compromise performance.
UVC Curing: On the other hand, UVC light cures the topmost 1–2 micrometers of the coating. This precision is essential for achieving a smooth, glossy finish with high resistance to environmental wear and tear.
Advantages of Combining UVC and UVA Curing
Enables UV LED curing of conventional UV coatings
UVC LED light can support the curing of coatings originally developed for conventional UV mercury lamps, enabling the possibility of transitioning to energy-efficient UV LED curing.
Energy Efficiency
UVC curing requires less energy than thermal curing processes. When integrated with UVA curing, it creates a balanced system that optimizes energy consumption while achieving comprehensive curing.
Enhanced Surface Properties
The UVC spectrum is particularly effective in curing the surface layer to a high gloss, reducing micro-scratches and enhancing abrasion resistance.
Improved Mechanical Strength
UVA light ensures the deeper layers are fully cured, resulting in a coating that can withstand mechanical and chemical stresses, and prolonged exposure to harsh environments.
