The compression between buildings often leads to cracks, sand holes, and holes in many walls. Rainwater seeps through these cracks into the walls, washing away to the exterior wall surface, where leakage stains appear on the interior walls.

Environmental factors' impact on the aging of structural adhesives

1. During the actual application of curtain walls, it is inevitable to be affected by surrounding environmental factors. Such as: rainwater, ultraviolet radiation, and high temperatures, which can cause discoloration, bubbling, cracking, and even脆ification, cracking, and delamination during use, reducing the service life and severely affecting the safety of the curtain wall project.
2. The glue application is not dense; there is no proper control over the amount of glue at the joint area during the glue collection, resulting in too thin a glue thickness. Since the aging of weather-resistant glue progresses from the surface to the depth, insufficient depth of the glue will lead to premature cracking and leakage. If the sealing of threaded holes is not tight or there are omissions, it will form water leakage paths.
