It offers exceptional adhesion across diverse materials, high elasticity for vibration resistance, and a paintable finish. Resistant to fresh and saltwater, it meets strict marine standards while maintaining low emissions for an eco-friendly, low-odour experience. ## 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.
