AEXZR 9900 Waterproof Silicone Structural Sealant | 950 kPa Bond, Flexible, UV-Resistant | 300ml | Black / Clear / Grey / White

Stop leaks, cracks, and gaps for good. The AEXZR 9900 Waterproof Silicone Structural Sealant delivers a professional-grade, permanent bond on virtually any surface — no metal fixings, no frames, no specialist tools required. Simply apply, and let it cure to a strong, flexible, weatherproof seal.

💪 950 kPa Bond Strength
Exceptional adhesion that resists heavy loads and structural stress. Bonds two surfaces together with the reliability of mechanical fixings — ideal for structural glazing, curtain walls, and load-bearing joints.

💧 Superior Waterproof Sealing
Fills and seals gaps, holes, and cracks to form a watertight barrier. Prevents water ingress, mould growth, and water damage in both indoor and outdoor applications.

🧲 Flexible After Curing
Unlike rigid adhesives, this sealant retains its elasticity after curing. It absorbs movement, vibration, wind oscillation, seismic activity, and thermal expansion — preventing cracks and joint failure even under sustained stress.

⚡ Fast-Drying Formula
Smooth, bubble-free formula cures quickly to a glossy, professional finish. Apply directly from the tube or with a nozzle for precise, clean results. Neutral cure with a mild, non-irritating odour — safe for enclosed spaces.

🌡️ UV & Weather Resistant: −50°C to +150°C
Withstands daily UV exposure, rain, humidity, frost, and extreme heat without melting, cracking, shrinking, or degrading. Maintains its seal and bond strength in all climates and seasons.

🔧 Bonds to Almost Any Surface
Adheres to glass, brick, concrete, aluminium, metal, mortar, cement, tiles, and more. Suitable for structural glazing, roofing, curtain walls, aquarium glass, window and door manufacturing, and all architectural panel sealing and jointing.
