Ultraviolet Catalysts

Ultra violet or UV catalyst also known as a photoinitiator, can be mixed with resins, which then cure when exposed to UV light (either natural sunlight or artificial lighting). When radiant energy (i.e., the UV light) cleaves an atom from the photoinitiator molecule, a free radical is created that acts similarly to a peroxide-type catalyst, linking with the resin molecules and causing rapid crosslinking. Brand names of pre-mixed UV resins include Solarez and Suncure.
