Ordinary sealant only serves the functions of filling cracks and waterproofing, and its adhesive bearing capacity is insufficient. The self-weight, wind pressure, and temperature-induced deformation loads of curtain wall glass are significant, requiring structural sealant to provide high-strength adhesive for bearing and supporting. The ShuangyuanSY-9900 is a neutral silicone structural sealant that has high tensile bonding strength, can firmly fix the glass panel, withstand the long-term external forces of the building, and ensure the overall safety of the curtain wall.
