Overview of hot melt adhesive

Hot melt adhesive is a kind of plastic adhesive, which can be used in arts and crafts, electrical appliances, clothing, toys, book packaging and other industries. Within a certain temperature range, the physical state of the hot melt adhesive changes with temperature, while the chemical properties remain unchanged. Hot melt glue is a kind of non-toxic and tasteless environmentally friendly glue. The adhesive is melted to 180-150°C twice in an oven, and then the composite material is pressed on the surface in the oven.

Generally speaking, the bonding of hot-melt adhesive is to melt the hot-melt adhesive through a hot-melt adhesive machine. The melted glue becomes liquid, and then is sent to the surface of the object to be adhered through the hot-melt adhesive gun and hot-melt adhesive tube of the hot-melt adhesive machine. After the hot melt adhesive cools, the bonding is complete. In order to give full play to the advantages of hot-melt adhesives in bonding, high-quality hot-melt adhesives must be used to match the corresponding quality and reliable hot-melt adhesive machines.

The hot melt adhesive spraying machine is a small manual spraying machine, just put the glue into the container, and then adjust the temperature to about 100-150 degrees, then it can be used continuously. This machine is generally suitable for small areas such as cartons, wood products, veneers, bags and so on. The hot melt adhesive is solid at room temperature and becomes liquid after heating, which reduces the amount of coating, saves costs, and has a wide range of applications.

The main uses of hot melt adhesive are: furniture edge banding; home decoration; book binding; leather glue; shoe production; hot melt adhesive cloth, etc. It can also be sprayed, which is impossible with any solid hot melt adhesive, so it can be applied to product surfaces of various shapes. It can also be brushed by hand after the small rice cooker is heated, which is very convenient for the application of small products.
