E-paper edge bond is a bonding agent especially for use on electronic paper. As it is used for electronic paper, it has not only excellent sealing properties but also excellent insulating properties. This ensures safety in use. E-paper edge sealants can be divided into two categories according to their composition, i.e. one-component and two-component.

One-component and two-component edge sealants have their own advantages and disadvantages. Here are some of their main advantages, disadvantages and differences:

1, the advantages of one-component electronic paper edge sealing adhesive: one-component electronic paper edge sealing adhesive has the advantages of fast curing, environmental protection, solvent-free, high light transmission rate after curing, suitable for electronic paper display edge sealing and protection, to avoid the disadvantages of two-component edge sealing adhesive need to wait for curing.

2、Disadvantages of one-component electronic paper edge sealant: the viscosity of one-component electronic paper edge sealant is high, which requires the use of special edge sealing machine and requires high operating skills.

3, the advantages of two-component electronic paper edge sealing adhesive: two-component electronic paper edge sealing adhesive has good adhesive performance and chemical resistance, suitable for a variety of materials, electronic paper display edge sealing, and can be added to control the viscosity of thickeners.

4, the disadvantages of two-component electronic paper edge sealing adhesive: two-component electronic paper edge sealing adhesive price is higher, not suitable for small-scale production.

The difference between one-component electronic paper edge sealer and two-component electronic paper edge sealer are:

1, the difference in performance: conventional one-component encapsulation adhesive performance in hardness and wear resistance, chemical resistance performance and many other aspects of the two-component paint effect has a slight gap between the main two drying film curing mechanism is not the same, as well as with the base village surface bonding force are different. However, the current epoxy one-component encapsulant of Microcrystalline Technology, prepared by adding the stone amount of alkene components, has substantially improved the performance of various aspects.

2, storage, transport differences: two-component encapsulant construction process is relatively complex, need to be proportionally blended and mixed evenly before construction; one-component does not need to be prepared, can be directly constructed, to overcome the shortcomings of two-component material blending and mixing unevenly and affect product quality, simple and easy to operate.

3, the construction of the difference: two-component encapsulation adhesive construction is not convenient, dry very slowly, the actual drying time takes an hour or even a few days, seriously affect the next step of the process; and one-component encapsulation adhesive is the opposite, easy construction, short drying time, does not affect other processes.

Therefore, the choice between a one-component or two-component e-paper edge sealer needs to be weighed against the specific application scenario and needs. If a faster drying time and simpler application are required, choose a one-component e-paper edge sealer; if better performance and a more complex mixing process are required, choose a two-component e-paper edge sealer.

WJ-EP1319M is a graphene enhanced modified high toughness one-component epoxy edge sealer developed by Vigon Technology. It has good flow properties and good toughness of the adhesive layer. It has excellent adhesion to metal, glass, PET and PS, etc. It is specially designed for the sealing of electronic paper modules.
