Structural Silicone Sealant - Sealing Joints in Metal Panels with Long Lasting Durability
Features
- The product is a single-component, neutral-curing, room-temperature vulcanizing (RTV) silicone sealant.
- It demonstrates non-corrosive behavior toward bonded surfaces, preserving substrate integrity.
- The sealant exhibits excellent weathering resistance, including high tolerance to ultraviolet exposure, elevated temperatures, and humid conditions.
- Thermal stability is maintained across a broad temperature spectrum, ranging from -50℃ to 180℃ in the fully cured state.
- The material possesses a joint movement capability of ±25%, accommodating structural displacement.
- It provides high-strength structural bonding with significant load-bearing performance under mechanical stress.
- Adhesion tAdhesion testing confirms strong bonding to multiple substrate types without the application of a primer in most cases.
- The formulation is characterized by low volatile organic compound (VOC) emissions, aligning with recognized environmental standards
Applications
- The sealant is applicable to structural sealing and glazing in high-rise curtain wall systems, encompassing aluminum, terracotta, and metallic facade constructions.
- It serves as a structural adhesive for the attachment of various panel systems in architectural and engineering contexts.
- The product is suitable for additional structural glazing applications within the construction sector.
- It is employed in the bonding and sealing of glass assemblies, including skylights, canopy structures, and glass balustrade systems.
- The material is applicable to structural bonding in photovoltaic module assembly and solar panel mounting infrastructure.
- It is utilized in sealing and bonding operations within the transportation industry, covering marine, recreational vehicle, and specialty vehicle applications.
- The sealant is appropriate for structural assembly and weatherproofing in prefabricated modular construction and industrial building envelope systems.
