Sikaflex 11 FC+ is a one‑component, moisture‑cured polyurethane sealant and adhesive designed for joint sealing with permanent elasticity. It provides high movement capability (approximately ±35 % according to ASTM C‑719) and maintains elasticity with Shore A hardness around 37 and tensile strength about 1.5 N/mm². The material shows elastic recovery of roughly 80‑90 % and resistance to many chemicals.
