Edge sealing hot melt adhesive has different affinity with different bonding materials. In order to make the hot melt adhesive play a better "viscosity", the following factors should be carefully considered when selecting edge sealing hot melt adhesive:

1. color Because the color of the adhesive is different, the color requirements of the edge sealing adhesive should be different. If the adhesive itself has no special requirements for color, it is recommended to use yellow edge sealing hot melt adhesive. In general, yellow edge sealing glue is better than white. 2.Surface treatment of adherend Edge sealing hot melt adhesive is not as strict as other adhesives on the surface of the adhesive, but the dust and oil on the surface of the adhesive should also be properly treated to make the edge sealing adhesive play a better role in adhesion.

3. opening hours Fast operation is a major feature of hot melt adhesive. The operation time of edge sealing glue is generally about 15 seconds. With the wide application of modern assembly line production methods, the opening time of edge sealing hot melt adhesive is required to be shorter and shorter. 4. heat resistance and cold resistance Edge sealing hot melt adhesive is sensitive to temperature. When the temperature reaches a certain temperature, the hot melt adhesive begins to soften; when it is lower than a certain temperature, the edge sealing adhesive will become brittle, so the choice of edge sealing hot melt adhesive must fully consider the change of ambient temperature.

5. viscosity The viscosity of EVA hot melt adhesive is divided into early viscosity and late viscosity. Only when the early viscosity and the late viscosity are consistent can the edge sealing glue and the bonded object remain stable. Should choose to have good anti-oxygen, anti-halogen, anti-acid alkaline and plastic edge sealing hot melt adhesive, in order to achieve good sealing effect, can not blindly pursue low-cost products.
