Raw Materials and Properties of Photosensitive Resin

Raw Materials and Properties of Photosensitive Resin

Photosensitive resin, also known as light-curable resin, is an oligomer that undergoes rapid physical and chemical changes upon exposure to light, enabling it to crosslink and solidify within a relatively short period. It consists of resin monomers and prepolymers, among other components, and contains reactive functional groups. When exposed to ultraviolet or visible light, it triggers a polymerization reaction initiated by a photoinitiator, ultimately forming an insoluble coating film.
