Guides and insights related to polyurethane sealant applications.

After the curtain wall project is completed, how long is the warranty period for the structural sealant typically?

Silicone sealant manufacturer note: structural sealant warranty terms are typically defined by the project contract/specs, while product warranty follows Shuangyuan’s 3-year policy and TDS (contact us for selection support such as SY-9900 where applicable).

Do you know the difference between silicone structural sealant and silicone weatherproof sealant?

Silicone sealant manufacturer note: weatherproof sealant focuses on joint sealing and exposure resistance, while structural sealant is for load-bearing bonding/structural glazing—select per project specs and the product TDS.

How can one determine whether the phenomenon of blistering is caused by the silicone sealant itself or by the substrate?

A simple way to distinguish bulging vs bubbling and assess whether the issue is more likely related to the sealant or the substrate, based on surface appearance and cross-section inspection.
