E-paper display technology has been developed for two or three decades and has many advantages such as ultra-low power consumption, paper-like feel, visible in sunlight, zero power consumption in constant light, eye protection without blue light, thinness, ultra-wide viewing angle, etc. Using e-paper display technology can bring many conveniences and comfortable experiences to everyone. With the development of today's technology and applications, e-paper has been widely used in a variety of scenarios and fields, and in all sizes.

In the process of using electronic paper, in many cases there will be moisture and air on the electronic paper corrosion and oxidation phenomenon, therefore, the use of a good edge sealer can be more effective in reducing the corrosion and oxidation of electronic paper module phenomenon, Vigon Technology developed a high toughness graphene modified UV curing edge sealer. The product has a short curing time, only 15s of UV light is needed, easy construction, long process window, and has excellent water vapour barrier properties after curing. The adhesive layer has good toughness and high adhesion to glass, metal, PET and other materials, so it has excellent results in the sealing of electronic paper modules.

UV light curing of UV e-paper edge sealant is a fast, efficient and environmentally friendly curing method that is widely used in printing, painting, electronics, optoelectronics and optics. The following will introduce the principle of UV electronic paper edge sealant curing.

UV paper edge curing is a process that uses ultraviolet light (UV) to cure the glue containing the photoinitiator (PI). UV light has a high energy and short wavelength and can penetrate transparent materials such as glass and plastic. When UV light is directed at the glue containing the photoinitiator, the initiator absorbs the energy and is converted into free radicals, which in turn trigger a cross-linking reaction that transforms the glue from a liquid to a solid.

Overall, the principle of UV electronic adhesive curing is to use UV light or electron beam to activate the photoinitiator to produce free radicals, which trigger the cross-linking reaction of the paint or glue, ultimately achieving fast, efficient and environmentally friendly curing.

The advantages of UV electronic adhesive curing are fast curing speed, low energy consumption, good curing effect, no volatile organic compounds and harmful gases, etc. Therefore, it is widely used in various fields and has become an important curing method.
