UV Initiator
Cationic photoinitiators mainly include diazonium salts, diaryliodonium salts, triarylsulfonium salts, alkylsulfonium salts, iron aromatic hydrocarbon salts, sulfonyloxyketones and triarylsiloxy ethers. Through the continuous enrichment and improvement of products in recent years, their applications have become more popular, and they are also an important part of the light curing application system.
