1. Description of Products

Photo Initiators (PI) are a kind of special organic compounds which absorb ultraviolet 250~420nm or visible light 400~800nm, produce free radicals or cations and trigger monomer polymerization. According to the photolysis mechanism, they can be divided into two categories: (1) Free radical polymerization photo initiators and (2) Cationic polymerization photo initiators.
