Sika Sikaflex 291 Sealant 150ml Black Polyurethane Elastic Bonding is a non-sag, 1-component polyurethane sealant designed for marine applications, curing upon exposure to moisture.
Sikaflex®-291 is a versatile sealant ideal for marine constructions, providing elastic and vibration-resistant joint seals. It adheres well to various materials commonly used in marine environments, including wood, metals, and ceramics. This product is suitable for both exterior and interior sealing applications but should not be used on plastics prone to stress cracking. Once cured, it can be sanded as needed. Designed for professional use, it is essential to test adhesion and compatibility with actual substrates.
