Super Glue Black RTV Silicone Instant Gasket

Super Glue's Black RTV Silicone Instant Gasket (SUPN80046) is a room-temperature-vulcanising silicone adhesive and sealant designed for creating flexible, durable gasket seals in modelling and hobby applications. It bonds and seals surfaces that need resistance to movement, vibration, or moisture, making it a practical choice where standard plastic adhesives or cyanoacrylates aren't suitable. The black finish blends neatly where a dark seal is needed.

Key Features

• RTV (room-temperature-vulcanising) formula cures to a flexible, rubber-like seal without heat
• Suitable for bonding and sealing metal, plastic, and rubber surfaces common in hobby and model assembly
• Black colouration makes it a discreet choice for joints and seams where appearance matters
• Remains flexible after curing, so it handles vibration and minor movement without cracking
• Applies directly from the tube for controlled placement on small or detailed work
