The aging of hot melt adhesive is quite common in its application. This phenomenon is mainly caused by the glue heating time being too long or the heating temperature being too high. How to determine if hot melt adhesive has aged?
Aging hot melt adhesive may exhibit the following phenomena:
The aging phenomenon that occurs is generally caused by improper use of hot melt adhesive. It can also be stored for a long time before use. The surface of hot melt adhesive begins to oxidize, attaching dust and microorganisms. As long as the storage space is dry, tidy, and used properly, hot melt adhesive can be stored better, and there is no need to worry about its good storage performance.

plum rain seasonHot melt adhesive granulesAgglomeration, mostly not due to glue spoilage, but ratherMoisture absorption+temperature fluctuationCausing mutual adhesion between particle surfaces. The principle of handling is simple: mild adhesion can be spread out and left to air, and after being dispersed, it can be used as usual; If there is obvious moisture absorption, whitening or […]
Why is it easy to clump in summer When the temperature is high,Hot melt adhesive granulesThe surface will slightly soften and adhere to each other, with severe cake formation throughout the bag, blocked feeding ports, and uneven adhesive glue. This is not a quality issue, the main reason is that the “storage temperature” and “softening […]
