The chemistry behind a sealant determines its performance — flexibility, adhesion, durability, and application. Understanding the resin type ensures the right sealant for every joint, substrate, and environment.
Silicone sealants are the gold standard for flexibility and weather resistance. These RTV (Room-Temperature-Vulcanizing) formulations cure by reacting with atmospheric moisture, forming a durable, rubber-like seal that remains flexible across extreme temperature ranges (-60°C to +250°C). With exceptional UV stability and water resistance, silicone sealants are the preferred choice for exterior applications where long-term performance is critical.

Polyurethane sealants offer exceptional durability, abrasion resistance, and superior adhesion to most surfaces including concrete, wood, metal, and masonry. They cure by reacting with moisture to form a tough, elastic seal that can be painted and is ideal for high-traffic areas. These sealants maintain their integrity under mechanical stress and are resistant to oils, greases, and fuels.
Key Properties

Acrylic and latex sealants are water-based, low-odor formulations that are easy to apply and clean up with water. They are paintable and ideal for interior applications where high flexibility is not required. While cost-effective and user-friendly, they offer lower durability and flexibility compared to silicone or polyurethane — making them best suited for low-moisture, low-movement interior gaps.

Polysulfide sealants offer exceptional resistance to jet fuel, aviation fuels, solvents, and petroleum products. These two-component systems cure to form a tough, flexible seal that withstands chemical attack and extreme conditions. While expensive, they are the preferred choice for aviation, marine, and industrial applications where fuel and solvent resistance is critical.

Butyl rubber sealants are synthetic rubber formulations that remain permanently tacky and flexible. They provide excellent airtight and watertight seals with superior adhesion to various substrates including glass, metal, and concrete. Their self-healing properties make them ideal for roofing and automotive windshield installation, though they have low UV resistance and are typically used in applications where UV exposure is limited.

Modified Silane (MS) Polymer sealants are the modern hybrid solution, combining the flexibility of silicone with the paintability of polyurethane. These solvent-free, odorless formulations bond to almost everything including concrete, wood, metal, plastics, and glass. With excellent UV stability and eco-friendly properties, MS polymers have become the preferred choice in modern construction for their versatility and sustainability.

From skyscrapers to ships, from highways to homes — sealants play a critical role in protecting structures, ensuring safety, and extending service life across every industry.

KNOWLEDGE CENTER
We offer a comprehensive range of sealants including silicone (RTV), polyurethane, acrylic/latex, polysulfide, butyl rubber, and MS polymer sealants — each engineered for specific applications, substrates, and environmental conditions across construction, infrastructure, industrial, and marine sectors.
Silicone sealants offer exceptional flexibility, UV resistance, and temperature tolerance (-60°C to +250°C) — ideal for glass, glazing, and exterior applications. They are not paintable. Polyurethane sealants provide superior adhesion, durability, and abrasion resistance — ideal for concrete, wood, and structural applications. They are paintable and excellent for high-traffic areas. The choice depends on the specific application requirements.
MS (Modified Silane) polymer sealants are modern hybrid solutions combining the flexibility of silicone with the paintability of polyurethane. They are solvent-free, odorless, and bond to almost all substrates including concrete, wood, metal, plastics, and glass. Their eco-friendly properties, excellent UV stability, and versatility have made them the preferred choice in modern construction and green building projects.
For expansion joints in concrete structures, we recommend polyurethane or silicone sealants. Polyurethane sealants offer excellent adhesion, durability, and abrasion resistance — ideal for floor joints, bridge joints, and highway joints. Silicone sealants provide superior flexibility and weather resistance — ideal for facade joints and exterior applications. The selection depends on movement capacity, traffic exposure, and environmental conditions.
Our technical team assesses your project requirements including substrate type (concrete, wood, metal, glass), joint movement, environmental conditions (indoor, outdoor, UV exposure, temperature), chemical exposure, and aesthetic needs (paintability, color). We provide detailed proposals with product specifications, application guidelines, and compliance documentation. Contact us for a free consultation.
All our sealants meet international standards including EN 1504 (concrete protection), ASTM C920 (sealants), ISO 9001 certified, and are SGS tested for quality assurance. Products are tested for adhesion, flexibility, weathering, UV stability, water resistance, and mechanical properties to ensure long-term performance and reliability.
