Electronic paper, also known as digital paper. Electronic paper is essentially a type of flat panel display technology, also known as electronic ink screen, which can imitate the visual sensation of printing and writing on paper. Electronic paper products are bendable, ultra-thin and light, and can maintain their displays even when the power is off.

Current electronic paper in the market has a very wide range of uses, electronic paper because of passive light-emitting with paper-like image storage display characteristics, with ultra-low power consumption to replace a single image and is widely used in e-books, electronic shelf labels and other paper-like display field. The development of high-resolution display technology that can dynamically change has become a sought-after goal, requiring display materials that are thin, bendable, and have a surface structure similar to paper, thus qualifying them to become a new generation of paper.In the electronic paper market, electrophoretic electronic paper occupies a high position. The principle of electrophoretic electronic paper: under the action of an electric field, electrophoretic particles are made to move in the electrophoretic solution, these particles are surface treated to be charged or individually uncharged, so that the various particles form the desired arrangement to display images and text.

General electronic paper structure includes substrate, electronic paper layer and protective film, and generally will be set in the electronic paper layer on one side of the protruding ears, set in the ears for connecting the electronic paper layer and the substrate of the ear hole, ear hole in the point of silver paste to conduct the substrate on the ito layer and electronic paper on the ito layer, due to the ear hole in the cleaning, need to wipe with alcohol, and ear hole inside the existence of gas, when the electronic paper layer and When the electronic paper layer and the substrate are laminated, the gas is sealed, but in a high temperature environment, the gas will slowly invade the visible area of the electronic paper under thermal expansion and contraction, thus leading to water, drums, substrate over hole corrosion and other phenomena, which seriously affects the quality and service life of the electronic paper.So, what are the properties of a potting compound for use on electronic paper?

1. Adhesiveness is important. It is the fundamental of edge sealing adhesive and its role is crucial.

2、Curing speed is important. Different types and brands of edge sealant, curing speed is different. But the curing speed directly affects the production speed and efficiency of the assembly line.

3、 Waterproofness is important. Normally, the good bonding of edge sealant means that the waterproof effect is also very good. Solid bonding with electronic devices, naturally able to block the entry of moisture, moisture and other water, to avoid the impact of components;.

4、Flame retardancy is important. In electronic paper as well as electronic products in the use of scenarios, there will inevitably be overload high temperature and other conditions, flame retardant performance is more advantageous.

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 frame sealant made by Microcrystalline Technology through a specific technical ratio.It improves the overall toughness and strength of the sealant, avoiding the shortcomings of similar products such as brittleness, low impact and peel strength; it has low water permeability, fast low temperature curing and other characteristics, suitable for assembly line efficient assembly production, improving production efficiency and reducing costs.
