Chemical & Material
Photoinitiator, known as a photosensitizer or the photocuring agent, it is a type of compound which is capable of absorbing energy of certain wavelengths in the ultraviolet region (250 ~ 420nm) or in the visible region (400 ~ 800nm) to generate free radicals, cations, giving rise to a crosslinking and polymerization of the monomer. Photoinitiator is a key component of light-curing materials, which plays a decisive role to the light curing speed.
