Photoinitiators Market - By Type: Type I (Acylphosphine Oxides, Benzoin Ethers), Type II (Benzophenones, Amines), Cationic Photoinitiators, Dual-Cure and LED-Optimized Systems; By Application: Printing Inks, Coatings (Wood, Plastic, Metal), 3D Printing Resins, Adhesives & Sealants, Electronics & Optics, Others; By Region: North America, Europe, Asia-Pacific Latin America and Others
1 | Market Overview
Photoinitiators are chemical compounds that absorb UV or visible light and initiate polymerization in radiation-curable systems. These critical additives are used in inks, adhesives, coatings, and 3D printing resins, enabling instant curing and environmentally friendly processing. As industries seek energy-efficient, low-VOC technologies, photoinitiators are becoming integral to advanced materials, packaging, electronics, and healthcare sectors.
The market segments into free-radical and cationic photoinitiators, with further classifications into Type I (unimolecular cleavage) and Type II (bimolecular hydrogen abstraction). Hybrid systems that combine dual-cure mechanisms are also gaining traction.
