Easmer company's polyester acrylate oligomers are widely used in the ink industry due to their good dispersibility and stability. This product can significantly enhance the printing effect and color vividness of inks, bringing revolutionary changes to the ink industry.
The main characteristics of cationic photoinitiators include light activation, proton acid generation, and initiation of cationic polymerization. Cationic photoinitiators absorb photons under UV or visible light, causing molecules to enter an excited state, followed by a series of decomposition reactions that ultimately produce proton acids (Brønsted acids or Lewis acids). These acids act as active species for cationic polymerization, capable of initiating the polymerization of epoxides, vinyl ethers, lactones, aldehydes, cyclic ethers, and more.
Applications of cationic photoinitiators
Cationic photoinitiators are widely used in various fields, including but not limited to:
Epoxy resins: Used for manufacturing electronic components, coatings, and adhesives.
Vinyl ether resins: Used for manufacturing plastics and composite materials.
Lactones, aldehydes, cyclic ethers: Used for manufacturing high-performance materials and specialty chemicals.
Classification of cationic photoinitiators
Based on chemical composition, cationic photoinitiators can be classified into the following categories:
Iodonium salts: Have high photosensitivity and stability.
Sulfonium salts: Suitable for various substrates with good solubility and reactivity.
Boron salts: Suitable for specific polymerization reactions with high catalytic efficiency.
These classifications allow cationic photoinitiators to adapt to different application needs and exhibit excellent performance under specific conditions.
