Usage

Photoinitiator 907 (CAS 71868-10-5) is an efficient photoinitiator, which is used in painting and electronics industries.
Offset, flexo, screen inks and electronic coatings. UV photoinitiator 907 can absorb ultraviolet radiation energy to form free radicals or cations during the curing process of ink. It can initiate polymerization, crosslinking and grafting of monomers and oligomers, and solidify the ink into three-dimensional reticulated polymer in a short time.
Photoinitiator 907 is a new type of highly active photoinitiator with high photoinitiator efficiency. It is often used with the photoinitiator of sulfur anthrone to enhance the absorbance. It is used to initiate rapid solidification of acrylates and methyl methacrylate.
