The compression between buildings leads to many walls developing cracks, sand eyes, and holes. Rainwater seeps into the walls along these cracks, washing onto the exterior walls and causing water leakage into the interior walls.

Environmental factors' impact on the aging of structural adhesives

In 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 can lead to discoloration, bubbling, cracking, and even脆ification, cracking, and adhesive failure during use, reducing the lifespan and severely impacting the safety of the curtain wall project.
2. The adhesive application is not dense; there is no proper control over the amount of adhesive at the joint area during curing, resulting in too thin a bead 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. If the sealing of threaded holes is not tight or there are omissions, it will create water leakage paths.
