It offers exceptional resistance to fresh and saltwater, cures via humidity exposure, and provides durable, vibration-resistant elasticity. Paintable and odorless, it adheres strongly to a wide range of materials including wood, metal, glass, and fiberglass, making it an essential sealant for demanding professional applications. ## Description Resistant to fresh and salt water, as well as the strict requirements of various marine standards, Sikaflex-291i is the perfect sealant for the marine sector. Its high adhesion and elasticity make it the ideal sealant for particularly stressed joints in maritime environments. At the same time, the elastic property ensures that the joints are vibration resistant. Thanks to its unique polyurethane-based formula, the adhesive cures by humidity - at higher temperatures, this process is slightly faster, but slightly slower at lower temperatures.
