Photoinitiators

Photoinitiators are chemicals used in light-sensitive materials, like inks, coatings, and adhesives, to start a chemical reaction when exposed to light, especially ultraviolet (UV) light. When illuminated, these chemicals break down into reactive particles that trigger polymerization, transforming liquid resins into solid films. This process enables precise, fast curing with minimal heat, making photoinitiators essential in industries such as printing, dentistry, and manufacturing for efficient and controlled hardening of materials.
