SIKAFLEX®-291, Marine Adhesive/Sealant
Sikaflex-291 is a non-sag, 1-component polyurethane sealant specifically developed for the marine market; it cures on exposure to atmospheric moisture to form a durable elastomer. Sikaflex-291 meets the requirements set out by the International Maritime Organisation (IMO).
USE
Sikaflex-291 is a multi-purpose product for use in marine construction and 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.
