Optical Fiber Primary Coating Material UV Curable Coating Resin
Uv curable coating resin is a resin that can polymerize and solidify into a solid state.
The curing principle of UV light curing resin (UV curing resin) is different from the thermal curing principle of other resins, which must be cured by UV machine / UVLED light curing machine. This process involves ultraviolet light irradiation, so that the terminal functional groups of some polymer materials in the resin have sufficient activity to react again under the irradiation of ultraviolet light, thus realizing crosslinking and curing. This curing technology takes advantage of the characteristics of the microscopic angle of polymer, that is, the terminal functional groups of some polymer materials have strong UV photosensitivity. Only under the irradiation of ultraviolet light, these functional groups can have enough activity to react again, manifested as curing.
