Structural Silicone Sealant - Structural Bonding For Exterior Architectural Glazing Systems
Features
- Single-component, neutral-cure, room-temperature vulcanizing (RTV) silicone sealant engineered for structural applications.
- Chemically non-corrosive to all bonded substrates, ensuring surface integrity and long-term compatibility.
- Superior weatherability with exceptional resistance to ultraviolet radiation, thermal aging, and high-humidity environments.
- Maintains structural stability across an extended temperature range from -50℃ to 180℃ after full cure.
- Accommodates joint movement of ±25%, providing reliable performance under dynamic structural loads.
- Delivers high-strength structural bonding with excellent load-bearing capacity for demanding engineering applications.
- Exhibits strong adhesion to a wide variety of substrates including glass, aluminum, steel, and stone, typically without the need for primer.Formulated with low volatile organic compounds (VOC), meeting international environmental and safety standards.
Applications
- Provides structural sealing and glazing for high-rise curtain wall systems, including aluminum, terracotta, and metal facade structures.
- Suitable for the structural attachment of diverse panel systems in commercial and architectural applications.
- Applicable to a broad range of structural glazing installations in the construction industry.
Engineered for bonding and sealing glass assemblies in skylights, glass canopies, balustrades, and architectural glass structures.
- Designed for structural bonding in solar photovoltaic mounting systems and module frame assembly.
- Suitable for sealing and bonding applications in transportation sectors, including marine vessels, recreational vehicles, and specialty transport manufacturing.
Ideal for structural assembly and environmental sealing in prefabricated modular construction and industrial building envelope systems.
