Testing the durability of adhesives is a challenging task. Certain methods can help test the service life of adhesives, thus determining the actual time that a workpiece can be bonded. For example, exposure to high temperatures, aging processes, and high humidity levels. The most accurate way to determine the bonding time of a workpiece is to subject the workpiece to an aging process for a certain period of time.
The best way to estimate the bonding time is to compare a new product with a product whose service life and performance ratio in the aging test are already known, so as to evaluate the bonding life of the new product. The longer the required bonding life of a product is, the more important the aging test of the product becomes.
