Sikaflex-291 is a one component, low viscous, medium modulus, polyurethane-based sealing/adhesive compound. Sealing is simply applying a protectant to keep out water and dirt on your boat. Bonding is using an adhesive to "glue" two or more things together. Sikaflex-291 is an excellent sealant and is also appropriate for light bonding where adhesive strength is not required. White.
