High Viscosity Hot Melt Adhesive For Book Binding

                                              How to choose Hot Melt Adhesive For Book binding？

1. The color requirements of Hot Melt adhesives must be different. If the object being tracked has no special color requirements, it is recommended to use yellow Hot Melt Glue. In general, yellow Binding Agent are stickier than white ones.

2. Substrate surface treatment. The surface treatment of Hot Melt Adhesive is not as difficult as other adhesives, but the dust and oil stains on the surface of the object must also be properly treated, so that the hot melt adhesive can better play the bonding role.

3. Operation time. Fast performance is one of the main characteristics of hot melt adhesive. The working time of hot melt adhesive for book is usually about 15 seconds. With the wide application of modern production mode - assembly line, the working time of hot melt adhesive should be shorter and shorter. For example, the duration of hot melt adhesive for binding books and making loudspeakers is about 5 seconds.
4. Temperature resistance. Hot melt adhesive is sensitive to temperature. When the temperature reaches a certain degree, the hot melt adhesive begins to soften. Hot melt glue becomes brittle if it is below a certain temperature. Therefore, in the selection of books and periodicals hot melt adhesive should fully consider the change in the ambient temperature of the product.
5. Adhesion. The viscosity of hot melt adhesive can be divided into early viscosity and late viscosity. Only when the initial viscosity matches the subsequent viscosity can the hot melt adhesive remain stable and viscous. The adhesion of hot melt adhesives varies according to the material of the target object. Therefore, different hot adhesives should be selected according to different materials.
