Sikaflex®-11 FC+ is a one-component polyurethane sealant, adhesive, and filler that cures when exposed to moisture in the air, forming a strong, permanently elastic joint. The material is ready to use, easy to apply mechanically, and suitable for both interior and exterior applications. Thanks to its combination of high adhesion, non-shrinking properties, and vibration resistance, it ensures a reliable bond and long-lasting sealing in structures where joint stability is critical.

The product features excellent performance characteristics: the approximate curing rate is about 3 mm per 24 hours under standard conditions, and the skin formation time is approximately 60 minutes. The material retains its elasticity over a wide temperature range—from -40 °C to +80 °C in dry conditions, and can withstand up to +90 °C for short periods. In humid conditions, the operating range is up to +50 °C, and it can withstand temperatures up to +60 °C for short periods, making Sikaflex®-11 FC+ a practical solution for various construction and installation tasks.

Sikaflex®-11 FC+ is compatible with most common building materials, including concrete, plaster, wood, ceramics, metal, galvanized steel, and copper. The material can be used for bonding, sealing, and filling fairly wide joints, maintaining water resistance and elasticity throughout its service life. It is a versatile technical product for builders, installers, and specialists who need a reliable solution for sealing and bonding in a single material.
