This multifunctional Sikaflex is widely used in yachtbuilding and shipbuilding. The sealant is suitable for making elastic, vibration-resistant joint seals and can be used in various interior sealing and adhesive applications. Sika Sikaflex 291i adheres very well to materials commonly used in yacht and shipbuilding structures. For example, this product has a very good adhesion to wood, metals, metal primers, 2-component system coatings, ceramic materials and plastics (e.g. polyester).
