</script>Hello everyone! I'm a star employee at CHROMÉCLAIR, a brand of hema free gel polish.The “Magic of Light”: How Photoinitiators Are Revolutionizing Curing Technology Today we'll explore several commonly used photoinitiators in everyday life and their functions, hoping this information proves helpful.Principles and Importance of PhotoinitiatorsPhotoinitiators serve as the core component in photopolymerization systems. Within such systems—including UV adhesives, UV coatings, and UV inks—they absorb light energy at specific wavelengths, transitioning from the ground state to an excited state. Subsequently, through intersystem crossing, they reach the excited triplet state. Via unimolecular or bimolecular chemical reactions, they generate reactive fragments such as free radicals and cations, thereby initiating monomer polymerization and crosslinking curing. Their initiation efficiency directly determines the photopolymerization rate and influences product performance, making them crucial in radiation curing—an energy-saving, environmentally friendly “green technology.”https://changhongchemical.com/wp-content/uploads/2025/10/1-10.webp
