How strong is the hot melt adhesive
How strong a hot melt adhesive is depends on how well it fuses with the substrate. Adhesive penetration is moderate, which is of great help in the formation of good adhesion.
In the past, it has been proved from countless practices that no matter how sticky the colloid at room temperature is, it is only an appearance. Only those that can really stick firmly and firmly in the application can reflect the true performance of the hot melt adhesive. The size of the resultant force can directly reflect this. The strength of the initial adhesive force cannot directly reflect the strength of the adhesive force. It also depends on what material it is applied to. If the material is friendly to the hot melt adhesive, it will bond well.
In the face of a variety of materials in the world, hot melt adhesive is not omnipotent. Even if it is the same material, different processes are applied to it, which may affect the performance of adhesion. It can be seen that each hot melt adhesive has its own scope of application, in other words, its performance has a certain scope of application. When materials, gluing equipment, and hot melt adhesive properties are well matched, the performance, including adhesion, will be excellent. We have also verified this in many real practices.
To know how strong the adhesive force of hot melt adhesive is, it is necessary to obtain the answer in practical application, and different application scenarios will have different bonding effects. Moreover, the size of the adhesive force cannot directly indicate the quality of the bonding effect in practical applications, and the effect is matched to the needs, which is what we ultimately want.
