Sikaflex -291 is a multipurpose pro-duct for use in marine construction & maintenance. It is suitable for making elastic, vibration-resistant joint seals, and can also be used for a variety of interior and exterior sealing applications. Sikaflex -291 bonds extremely well to the materials commonly used in marine construction like wood, metals, metal primers and paint coatings (2-C systems), ceramic materials and plastics (GRP, etc.). Sikaflex -291 must not be used to seal plastics that are prone to stress cracking (e.g. Plexiglas, polycarbonate, etc.). Once cured, Sikaflex -291 can easily be sanded down as required.
