Are you tired of sealants failing under Dubai’s relentless sun and sandstorms? For hardware professionals and construction experts, finding a sealant that withstands extreme heat, UV exposure, and humidity is not just a preference—it’s a necessity for project durability and safety.
Silicon sealants emerge as the superior solution, offering unmatched resilience for outdoor applications in the UAE. This guide delves into why they excel, how they’re made, and how to choose the best options for your needs.

How it is Made: From Raw Material to Finished Product
Raw Material(s): The primary material is polydimethylsiloxane (PDMS), a silicone polymer derived from silica (sand) and methyl chloride. Additives include cross-linkers for curing, fillers like calcium carbonate for viscosity, and pigments for color.
Manufacturing Process: The process begins with the polymerization of silicone monomers to form PDMS base polymer. This is mixed with fillers, plasticizers, and catalysts in high-shear mixers. The compound is then degassed to remove air bubbles, packaged into cartridges, and cured through moisture-activated reactions (for acetoxy or neutral cure types) upon application.
Key Properties Derived from Manufacturing: The manufacturing imparts exceptional weather resistance through stable silicone bonds that resist UV degradation, and flexibility from the polymer chain structure, allowing movement without cracking in Dubai’s thermal cycles.
Quality Control: Quality checks include adhesion testing on substrates like glass and aluminum, elongation and tensile strength measurements, accelerated weathering tests for UV resistance, and checks for consistency in viscosity and cure time to meet standards like ASTM C920.
Essential Uses in the UAE Construction Landscape
Primary Application(s): In Dubai’s construction sector, silicon sealants are crucial for sealing expansion joints in high-rises, waterproofing windows and facades against sand and rain, and bonding glass in curtain walls. They prevent air and water infiltration, ensuring energy efficiency and structural integrity in projects from skyscrapers to villas. For hardware export businesses, supplying these sealants supports the region’s booming infrastructure development.
When selecting a supplier in Dubai, prioritize those with proven reliability, local stock availability, and compliance with international standards. Look for suppliers offering technical support and products tested for UAE-specific conditions.
