The compression between buildings often leads to cracks, sand holes, and holes in many walls. Rainwater seeps into the walls along these cracks, washing onto the exterior walls, causing leakage inside the building.

Environmental factors' impact on the aging of structural adhesives

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 lead to 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's a lack of control over the glue quantity during the sealing process, resulting in excessively thin glue thickness. Since the aging of weather-resistant glue progresses from the surface to the depth, insufficient depth of the glue leads to premature cracking and leakage. If the sealing around threaded holes is not tight or there are omissions, water leakage paths will form.
