What Wavelength is Best for UV LED Curing? What You Need to Know
What Wavelength is Best for UV LED Curing? As cured materials differ from each other, the best wavelength for UV LED curing also changes. What wavelength is best for UV LED curing? However, it is safe to assume that 365 nm, 385 nm, 395 nm, and 405 nm will cover most commercial and industrial applications. Each UV wavelength has its pros, and that must be taken into consideration. The wavelength range of 365nm nm to 405nm must match the required application to achieve better objectives, such as lowering cost and boosting performance. Process of Wavelengths and Photochemical Activation UV LED curing can emit photochemical reactions in glues, coatings, and even inks with the use of UV light, adhesives, coatings, and inks. The most frequently used wavelengths in UV LED curing include: These wavelengths fall into the range of UVA (315-400 nm), which is widely utilized in ultraviolet curing systems because of its efficacy and safety. Factors Affecting the Choice of Wavelength 1. Material Compatibility Photoinitiators, materials, and their construction elements respond more readily to specific wavelengths. As an example, some adhesives and coatings are made to be cured under 365 nm light; however, other formulations may require 395 nm or ...
