What is LED UV Curing Technology?
- Fundamentally, LED UV curing consists of subjecting a photopolymer to high-intensity UV light produced by LEDs in order to initiate photopolymerization. This is done to transform UV-sensitive substances, e.g., adhesives, coatings, and inks, that are in liquid or semi-liquid form into a solid within a few seconds. The LED curing lamps, in contrast to the traditional mercury-based UV lamps, have a high level of controlled wavelength, consume less energy, and have a longer service life.
- The ultraviolet LED curing systems exploit the wavelengths that are usually present in the 365nm to 405nm range to excite the photo initiators in the UV-curable materials. Scoring the wavelength to the photochemistry of the material enables the manufacturers to achieve the maximum possible speed of curing and depth of LED UV light, and obtain uniform results in all applications.
Important benefits of LED UV Curing
- Energy Efficiency: LED sources of high intensity use much less energy than the UV lamps of traditional sources, so that the use of eco-friendly LED UV curing is supported.
- Quick Cure: LED curing with high-speed lowers production cycle times, resulting in improved throughput with accurate energy application.
