Sika 90925 Sikaflex-291 LOT Marine Polyurethane Adhesive Sealant White 10.3oz

Sikaflex-291 LOT (Long Open Time) is a premium one-component marine-grade polyurethane adhesive and sealant designed specifically for boat building and repair applications. This professional-grade sealant offers nearly the same strength as standard Sikaflex-291 while providing slightly enhanced flexibility and a significantly extended working time due to its slower skin-over rate.

Key Features:

• Extended working time with slower skin formation for easier application and adjustment
• High-strength polyurethane formula bonds and seals virtually all marine substrates
• Excellent flexibility to accommodate joint movement and thermal expansion
• Superior adhesion to fiberglass, wood, metals, and gel coat without primers
• Outstanding resistance to saltwater, weathering, and UV exposure
• Remains permanently elastic after curing
• Paintable with most marine coatings after curing

Common Applications:

• General sealing and bonding throughout the vessel
• Hull-to-deck joints and hull seams
• Bedding deck hardware, hatches, and portlights
• Through-hull fittings and seacocks
• Rub rail installation and repair
• Structural bonding applications

The white color provides a clean, finished appearance suitable for visible applications. Each 10.3 oz cartridge is designed for use with standard caulking guns for precise, controlled application.
