What causes the condensation of the gift box glue?

Sometimes the gift box glue just bought back is not ready to be used, so it is stored in a warehouse or a cool place, but when it is time to use it is found that the gift box glue has already condensed. What is the reason for this? The gift box glue has been widely used because of its unique performance advantages, so what causes the gift box glue to coagulate?

In fact, this situation occurs mainly because the manufacturer has problems with end-point control during production. Under normal circumstances, we need to use viscosity to determine the pH value, temperature, raw material quality, etc. during the production process. These will have a certain impact, especially at the acidic stage. When urea is added for the second time, improper control of the polycondensation reaction will cause a sudden increase in viscosity and a non-flowing and elastic gel phenomenon.

Before using the gift box glue, the user must learn more about this knowledge to avoid quality problems. This requires the manufacturer to have such a wealth of experience in technology and experience, and at the same time have an understanding of the product. Therefore, we should buy it from a regular gift box glue manufacturer, so that the frequency of problems will be reduced a lot.
