Description
Sikaflex®-291 | White | 310mL Marine Polyurethane Sealant
Sikaflex®-291 is a high-quality, non-sag, one-part polyurethane sealant specifically formulated for marine applications. Designed for reliable sealing and bonding in demanding marine environments, it provides excellent adhesion, durability, and long-term weather resistance.
This low-odour, elastic formulation bonds effectively to a wide range of substrates commonly used in boat building and repair, including fibreglass, wood, metals, and various marine plastics. Once cured, it forms a tough yet flexible seal that can accommodate vibration, movement, and structural stress.
Sikaflex®-291 is non-corrosive and electrically non-conductive, making it suitable for sensitive marine installations. It can also be sanded after curing if finishing work is required, and it meets International Maritime Organization (IMO) requirements for marine use.
