Тестирование характеристик светоотверждаемых смол
A photocurable resin is a polymer material whose curing process is catalyzed by a photoinitiator under ultraviolet or visible light. Light curing resin is usually a single component material, то есть, it only needs to be coated on the substrate, through ultraviolet or visible light irradiation, can achieve rapid curing of the coating in a few seconds or minutes. Light curing resin has excellent heat resistance, химическая устойчивость, wear resistance and aging resistance, and has the advantages of low cost and easy to use, which is widely used in the coating and manufacturing process of 3D printing, электроника, оптика, printing and other fields.
