Functions and advantages of 4-Benzoylphenyl Methacrylate

Photoinitiator, also known as photosensitizer or photocuring agent, is a kind of compounds that can absorb energy of a certain wavelength in the ultraviolet region or visible light region, produce free radicals, cations, etc., thus triggering monomer polymerization and crosslinking curing. Photoinitiator has the characteristics of good stability, easy to store for a long time, good solubility and reactivity, less dosage, high initiation efficiency.

4-Benzoylphenyl Methacrylate

The free radical system has a fast curing speed but a large shrinkage. While cationic light curing volume shrinkage, strong adhesion, curing process is not hindered by oxygen polymerization, the reaction is not easy to stop, "post-curing" ability is strong, suitable for thick film light curing, but the curing speed is slow. Combining the advantages of the two, the hybrid system of free radical and cationic photoinitiator can not only induce cationic polymerization of free radical polymerization, but also make full use of advantages and avoid disadvantages, which has a synergistic effect. More than two photoinitiators are used together for better results.

4-Benzoylphenyl Methacrylate is a kind of excellent photoinitiator. It is also a kind of fine chemical.
