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).
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.
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.
