Most customers, after purchasing the aluminum paste, cannot use it up all at once, and save the rest for later use. If it is not stored properly, you will find that the material is no longer usable when you take it out next time. If the water-based aluminum paste is not stored properly, it will agglomerate for a long time, making it unusable. Some people have already preserved the aluminum paste, but this situation still occurs. Here is how to check whether the water-based aluminum paste can be used.

How to check water-based aluminum paste?

First: Check whether the outer packaging of the product is intact, and then open the package to check whether there is oxidation and agglomeration. The oxidized and agglomerated water-based aluminum paste will change from the original paste to a hard block. If there is a hard block, it means this The water-based aluminum paste has been oxidized and cannot be used.

Second: If the outer packaging of the water-based aluminum paste is in good condition, you can take out a small amount for testing. If there is no difference in the effect, it means that the water-based aluminum paste can still be used.

Third: carry out temperature resistance test. Put the finished water-based silver paint into a constant temperature oven at about 55℃ for testing. If the effect can be guaranteed for 7 days without obvious matting, gelation, etc., it can be stored for about half a year, and if the storage time can reach 14 days The above can basically be stored for 6 months to 12 months.

The above is an introduction to how to check whether the water-based aluminum paste can be used.

Before using the water-based aluminum paste, we must first check the integrity of the water-based aluminum paste, and observe whether the water-based aluminum paste in the packaging barrel is agglomerated or hardened. If it does, please stop using it immediately. Of course, in addition to the adverse reactions that we can see with the naked eye, there are some reactions that we cannot distinguish by appearance. This requires customers to conduct a sampling test for each batch of goods to ensure the stability of product quality.
