GMSA RTV Clear Silicone Sealant 310ml is a premium-quality one-part RTV (Room Temperature Vulcanizing) silicone sealant specially formulated to provide strong adhesion, waterproof protection, and long-lasting flexibility. It cures into a tough, durable rubber seal that performs exceptionally well in both indoor and outdoor applications. Whether you are sealing windows, installing sanitary fittings, repairing construction joints, or completing general maintenance work, it delivers professional-grade performance.
Designed for construction, industrial, and household applications, this sealant bonds effectively to concrete, ceramic tiles, marble, aluminum, glass, plastics, metals, and most non-porous building materials. In addition, it provides reliable sealing for pipes, wall cladding, window channels, skylights, mirrors, electrical insulation, and gasket applications.
Features
GMSA RTV Clear Silicone Sealant 310ml is manufactured using 100% silicone technology to provide superior flexibility and weather resistance. Furthermore, it remains permanently elastic after curing, allowing it to absorb movement without cracking or shrinking. As a result, it provides long-lasting protection against water, dust, moisture, and air leakage.
Moreover, the clear finish blends seamlessly with glass, ceramic, aluminum, and decorative surfaces, creating a clean professional appearance. Under normal conditions (25°C and 50% relative humidity), it forms a skin within approximately 10 minutes, cures within 24 hours for a standard bead, and reaches full cure in about 7 days.
