| application | photoinitiator 819 can also be used for colored UV curing plastic coatings. UV coatings have been widely used on plastic shells of various electronic and home appliance products due to their excellent performance and efficient production. however, the UV coating film does not cure well after adding color, resulting in poor adhesion of the coating film, as well as the poor dispersion and arrangement of pigments by UV resin, it seriously affects the appearance of the coating film. Therefore, the traditional construction process is to first coat solvent-based colored primer for coloring, and then coat UV varnish after baking to improve the various physical properties of the paint film surface. |
| overview | photoinitiator (Photoinitiator, abbreviated PI) is a key component of photocurable materials, which plays a decisive role in the photocuring speed of photocurable materials. Photoinitiator is a kind of material that can absorb radiation energy, undergo photochemical changes after excitation, and produce active intermediates (free radicals or cations) with the ability to initiate polymerization. Photoinitiators can be divided into ultraviolet initiators (ultraviolet light absorption region 250 ~ 420nm) and visible light initiators (visible light absorption region 400 ~ 700nm) due to different radiation energy. Photoinitiators can be divided into free radical photoinitiators and cationic photoinitiators due to the different active intermediates produced. Free radical photoinitiators can be divided into two types: cracking photoinitiators and hydrogen-dehydrating photoinitiators due to the different mechanisms of producing free radicals. At present, the light curing technology is mainly ultraviolet curing, and the photoinitiator used is ultraviolet light initiator. |
| use | UV curable varnish and paint systems, such as wood, paper, metal, plastic, optical fiber and printing ink and prepreg systems |
