Electronic paper product technology has many years of development history, with the continuous progress of electronic paper display technology, it has ultra-low power consumption, paper-like feel, visible in the sun, always bright zero power consumption, eye protection without blue light, thin, ultra-wide viewing angle and many other characteristics. Along with the development of the Internet of Things, electronic paper is widely used in diverse scenes and fields from centimeter to meter size level.

E-paper technology is a "microencapsulated electrophoretic display" technology. The basic principle is the migration of charged nanoparticles suspended in a liquid by the action of an electric field. E-ink is made up of millions of microcapsules. Each microcapsule contains electrophoretic particles - negatively charged white and positively charged black particles - suspended in a transparent liquid. Using the principle of positive and negative attraction, when the electric field is switched on, the black or white particles corresponding to that block will move to the top of the microcapsules, and the user will be able to see the white or black on that block.

As an important part of the raw material composition of electronic paper, edge sealant for electronic paper bonds the substrate of each sheet layer of electronic paper while maintaining a certain gap, and then seals the infused liquid crystal so that it cannot leak while preventing outside contaminants from entering, this adhesive is the frame sealant, also known as edge sealant. So, what are the characteristics of electronic paper edge sealant.

1、Bonding: this is the fundamental of edge sealing adhesive, the role is crucial.

2, flame retardant: in electronic paper and electronic products in the use of scenarios, there will inevitably be overload high temperature and other conditions, flame retardant performance is more advantageous;.

3, curing speed: different types and brands of edge sealant, curing speed varies. But curing speed directly affects the production speed and efficiency of the assembly line.

4、Waterproof: Normally, the adhesive of edge sealant is good, which means the waterproof effect is also very good. Solid bonding with electronic devices, naturally able to block the entry of water vapor, moisture and other moisture to avoid the components are affected.

As the electronic paper relies on microcapsules suspended in liquid display, the electronic paper surface layer and the bottom layer between the liquid containing microcapsules is fragile, easy to leak then affect the electronic paper performance, making the importance of electronic paper sealant more and more obvious; especially the current trend of electronic paper thin and light, flexible foldable, etc., the electronic paper sealant to put forward more demanding requirements. One-component epoxy electronic paper sealant is a new type of sealant made by Microcrystalline Technology through a specific technical ratio; it improves the toughness and strength of the sealant, avoiding the shortcomings of similar products such as brittle, low impact and peel strength; it has low water permeability, fast low temperature curing and other characteristics, suitable for assembly line efficient assembly production, improve production efficiency and reduce costs.
