Can hot melt adhesive be heated and used repeatedly? Hot melt adhesive needs to be heated and melted with a professional hot melt glue machine before construction and use, but sometimes the amount of use may not be accurately grasped, resulting in hot melt glue that is not used up in the glue tank. Can
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 confirmed from countless practices that no matter how sticky the colloid
The biggest hot melt adhesive manufacturer winlong from China In the course of more than 20 years of development, winlong has adhered to the service concept of "make good glue with heart, let customers use good glue, and help customers use glue well", and bring the most reliable glue experience to global customers. winlong is
Is hot melt adhesive the stronger the better? Adhesion is one of the core properties of hot melt adhesives. Whether the adhesive strength is high enough often affects the application effect of hot melt adhesives. But in actual use, is the stickiness of the hot melt adhesive as strong as possible? The viscosity of hot
Is hot melt adhesive toxic? The bonding speed of hot melt adhesive is fast, and its stable performance is conducive to sustainability. The automation technology tells the operation that it is very cost-effective. And in the process of using hot melt adhesive, no drying process is required, the bonding process is simple, the materials that
What glue is used for handbags? The topic of environmental protection is very much advocated in the whole country and even the whole world. As a packaging product, hot melt adhesive for handbags has gradually replaced the market of some plastic bags. The usage has also increased. Handbags can be divided into white cardboard handbags,
Is hot melt glue permanent? The viscosity of hot melt adhesives has different performances due to different adhesives, but it does not mean that the viscosity of hot melt adhesives is not good or unstable, but the adhesion effect that hot melt adhesives can achieve for different bonding areas will be. not exactly. In the
The important role of adhesives and bonding technology With the development of economy and science, adhesives are indispensable in industry, agriculture, transportation, medical care, national defense and people's daily life. Adhesives are involved with almost anyone and anything. Adhesives in my country started in the 1950s. After entering the 1990s, the adhesive industry has developed
Precautions for storage and storage of water-based sealing glue 1. Storage and transportation should be at 0°C-50°C, and avoid sunlight exposure. The molecular structure of glue below 0°C is easy to change, which will weaken or even fail the glue. 2. It is recommended to use it first to avoid expiration. The shelf life is
The quality of the surface treatment is often the key to the success or failure of a good adhesive joint, because the wettability of the adhesive to the surface of the adherend and the intermolecular force at the interface (that is, the adhesion force) are the main reasons for obtaining high bond strength. During the
