Sika 610564 Sikaflex-291 LOT Marine Polyurethane Adhesive Sealant White 3oz

Sika Sikaflex-291 LOT (Longer Open Time) is a premium one-component marine polyurethane adhesive and sealant designed specifically for marine applications requiring extended working time. This white 3 oz. tube formulation offers nearly the same bonding strength as standard Sikaflex-291 while providing slightly more flexibility and a slower skin-over time for easier installation.

Key Features:

• Longer open time allows for more working flexibility during application
• High-strength bonding with excellent elasticity for movement joints
• Exceptional adhesion to a wide range of marine substrates including fiberglass, wood, and metals
• Excellent UV and weathering resistance for long-lasting durability
• Suitable for above and below waterline applications
• Paintable after curing

Common Applications:

• Sealing hull seams and deck joints
• Bedding deck hardware, handrails, and rub rails
• Sealing thru-hulls and port lights
• General marine sealing and bonding throughout the vessel
• Bonding and sealing in areas requiring extended positioning time

This marine-grade sealant cures by reacting with atmospheric moisture to form a durable, flexible elastomer that accommodates movement while maintaining a watertight seal. The 3 oz. tube size is ideal for smaller projects and repairs.
