Although EVA hot melt adhesive is an excellent solution for many industrial applications, it requires careful control of the high temperature during the process to avoid smoke problems. When hot melt adhesives are heated, they inevitably release some smoke. That is the odor detected while working near the hot melt nozzle. Although some smoke is normal, excessive smoke indicates a problem with your process and requires attention.
Our team has seen examples of hot melt adhesive smoking and provided some tips on how to make adjustments to reduce the amount of smoke.

To prevent hot melt adhesive from smoking, please check your various hot melt adhesive process parameters:
Temperature:The temperature of the hot melt gun or glue coating equipment is crucial. When it is too low, the adhesive cannot melt and flow properly. Too hot, the adhesive will become too thin and release unpleasant and irritating smoke. In some cases, burnt adhesive can cause the final glue to change color and may also lead to carbonization. Adjust the temperature settings based on the manufacturer’s specifications for the hot melt equipment and the temperature recommendations for the specific adhesive you are using.
Coating equipmentCleanliness of work area:Adhesive residues near coating equipment, coating heads, and work areas can cause adhesive problems and smoke.. Burning and dried adhesives are more prone to smoking than fresh, unmelted hot melt adhesives. The accumulation of used dry adhesive on the application equipment is a common source of smoke.
InSunlife Hot Melt Adhesive, we can help you understand the reason why your hot melt adhesive dispenser is smoking. Always ensure that you follow the manufacturer’s guidelines for your adhesive equipment, modules, and hoses, as well as the hot melt adhesive you use.
EVA hot melt adhesive is suitable for a wide range of industrial applications, so make full use of your system and avoid uncomfortable and annoying smoke.
Analysis of aging reasons of EVA hot melt adhesive during use? Many customers encounter a decrease in viscosity and insufficient bonding strength of EVA hot melt adhesive after prolonged use. It is usually considered that the product quality is poor. However, this is not the case. This phenomenon is likely caused by the aging of […]
It is well known that books are usually bonded with hot melt adhesive. In the book binding, < a href = "http://www.sunlife888.com" > hot melt adhesive books < / a > can be piles of paper and adhesive in the cover of the book. There are various methods to complete the binding of books and […]
Using hot melt adhesive particles on the same material surface will provide better quality assurance, as hot melt adhesive is always sprayed on the material surface in a molten state – this helps to generate thermal reactions and increases adhesion compared to adhesives, without using heat during the bonding process. Stable quality provides good adhesion […]
The curing speed of EVA hot melt adhesive refers to the time from the beginning of adhesive bonding to the moment when the bonding strength reaches 80%. The curing time required for general use ranges from 1 second to 10 seconds, and the curing speed required for automatic sealing is generally within 4 seconds. There […]
