Ultraviolet (UV) light is a form of electromagnetic radiation that spans wavelengths from 10 nm to 400 nm, situated between visible light and X-rays. This region of the spectrum is crucial for various applications due to its ability to induce photochemical reactions. Photopolymerization is the process by which molecules known as monomers undergo a chemical change upon exposure to UV light, converting into a solid polymer. Photoinitiators, which are substances that absorb UV light and initiate the polymerization process, play a pivotal role in this transformation. When UV light is applied, photoinitiators generate free radicals or cations that react with the monomers, catalyzing their polymerization into a solid form. This process occurs rapidly, making UV curing an efficient method for solidifying coatings, adhesives, and inks in numerous industries.
