Testing the durability of adhesives is a difficult task. However, certain methods can help test the service life of adhesives, thereby determining the actual time that workpieces can remain bonded. Examples of such methods include exposure to high temperatures, aging, and high humidity.


The most accurate way to determine the bonding time of workpieces is to subject them to aging over a certain period. The best method to estimate the bonding time is to compare new products with those whose service life and performance in aging tests are already known, so as to evaluate the bonding life of the new products. The longer the required bonding life of a product, the more important the aging testing of the product becomes.
