Illustration of Window and Beam Leakage with Exterior Wall

The compression between buildings leads to many walls developing cracks, sand holes, and holes. Rainwater seeps into the walls along these cracks, washing away to the exterior wall surface, where it leaves leakage stains 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, UV radiation, and high temperatures. These factors can lead to discoloration, bubbling, cracking, and even脆ification, cracking, and delamination, reducing the lifespan and severely impacting the safety of the curtain wall project.
2. The adhesive application is not dense; there's no proper control over the amount of adhesive at the joint area during curing, resulting in excessively thin adhesive thickness. Since the aging of weather-resistant sealant progresses from the surface to the depth, insufficient depth of the sealant leads to premature cracking and leakage. In cases where the thread hole sealant is not applied tightly or is missing, it can create water leakage paths.
