What should be paid attention to when storing PU glue?

For the preservation and use of PU glue, the best storage environment temperature for PU glue is generally 15℃-25℃, and the humidity needs to be less than 65%.

If the temperature is too high, the curing agent will undergo a self-polymerization reaction, thereby accelerating the self-polymerization at a high temperature, then it will be easy to polymerize a part of the trimer to form a network structure, which will affect the toughness of the colloid, so generally The humidity needs to be greater than 65% of the environment, so that the ratio is unbalanced, which affects the characteristics of defoaming, surface dryness and curing

So how to store PU glue correctly? First, the general environment needs to be sealed and protected from light, so that it can be stored for three months. Then PU glue needs to be used up within one month when it has been opened and the lid should be closed.
