What Wavelength is Best for Spot Curing? About spot curing, selecting the proper wavelength of ultraviolet (UV) light is important. The answer to the problem “what wavelength is best for spot curing” is critical to achieving curing effectiveness, speed, and quality of the end product. In this writing, we will discuss the science that pertains to curing UV wavelengths and their uses, as well as how to select the best wavelength to meet your spot curing demands.  Why Wavelength Matters in UV Spot Curing? Best UV Wavelengths for Spot Curing In spot-curing systems, several UV wavelengths are used, which will be discussed below. Let’s analyze which one functions more effectively than the rest: 1. 365nm UV Curing  365nm UV Wavelength is a deep range classified under UV-A and is very popular for curing some adhesives, epoxies, and acrylics. It’s particularly popular in electronics, adhesive curing, and medical device bonding. This wavelength has many uses owing to its ability to penetrate deeply and thereby effectively penetrate thick materials.  • Advantages: Deep penetration, ideal for thick or pigmented materials.  • Applications: Electronics adhesive curing, optics bonding UV, medical device bonding UV.  2. 385nm UV Curing  Due to higher energy photons at 385nm, ...
