How It Is Made: From Raw Material to Finished Product
Raw Material(s): The primary materials for silicon sealants include silicone polymers (like polydimethylsiloxane), fillers (such as silica), cross-linkers, and catalysts. Additives like pigments and adhesion promoters are also used to enhance properties.
Manufacturing Process: The production begins with mixing silicone polymers with fillers in a high-shear mixer to achieve homogeneity. Next, cross-linkers and catalysts are added to initiate the curing process. The mixture is then degassed under vacuum to remove air bubbles, ensuring a smooth finish. It is packaged into cartridges or tubes, often with moisture-proof seals to prevent premature curing. The sealant cures when exposed to atmospheric moisture, forming a flexible, durable bond.
Key Properties Derived from Manufacturing: The process imparts essential properties like flexibility, allowing the sealant to accommodate movement and thermal expansion common in UAE structures, and weather resistance, crucial for withstanding extreme heat, UV exposure, and sandstorms. Additionally, it ensures adhesion strength to various surfaces, from glass to concrete.
Quality Control: Reputable manufacturers conduct tests for viscosity, extrusion rate, skin-over time, and full cure time. Adhesion tests on standard substrates, hardness checks, and accelerated aging tests simulate long-term performance. Compliance with international standards like ASTM C920 and ISO 11600 is mandatory for reliability.
Essential Uses in the UAE Construction Landscape
Primary Application(s): In the UAE, silicon sealants are primarily used for sealing joints in high-rise buildings, waterproofing bathrooms and kitchens, glazing applications in windows and facades, and expansion joints in bridges and infrastructure. Their resistance to temperature fluctuations and humidity makes them ideal for the region’s demanding environment, preventing leaks and enhancing energy efficiency.
