Hi Bond Foam Sealants/Flotation

Hi Bond Foam Sealants and Flotation Solutions for Marine Applications

When it comes to reliable marine flotation and insulation products, Hi Bond has established a strong reputation for their specialized two-part liquid urethane closed cell foam systems. These foam sealants and flotation products are engineered specifically for the demanding marine environment, where moisture resistance, chemical durability, and structural integrity are non-negotiable.

Hi Bond's two-part liquid urethane closed cell foam is designed for use in boat hulls and cavities for flotation or insulation purposes. What sets these products apart in the flotation category is their resistance to gas and oil contamination once cured, a critical feature for marine applications where fuel and lubricant exposure is inevitable. This chemical resistance ensures that the foam maintains its flotation properties and structural integrity even in bilge areas or fuel tank compartments.

Pour-in-Place Convenience and Performance

The pour-in-place application method offered by Hi Bond foam sealants provides significant advantages for boat builders and marine repair professionals. The mix ratio is 1 to 1, simplifying the mixing process and reducing the potential for application errors. Available in multiple sizes ranging from 2-quart kits to gallon configurations, these foam systems can accommodate everything from small repair jobs to large-scale flotation installations.

Hi Bond pour foam features a 2 lb. per cubic foot density, providing an optimal balance between buoyancy and structural support. This density specification makes the product suitable for Coast Guard flotation requirements while maintaining enough rigidity to support hull structures and prevent deformation under stress. The closed-cell structure ensures that water cannot penetrate the foam matrix, preserving flotation capacity over the life of the vessel.

Why Choose Hi Bond for Marine Flotation

For marine professionals working on hull repairs, custom boat builds, or flotation upgrades, Hi Bond foam sealants offer a proven solution that addresses the unique challenges of the aquatic environment. The cured foam provides dual functionality as both a flotation medium and thermal insulation barrier, helping to regulate cabin temperatures while maintaining essential buoyancy characteristics. Whether you're filling voids in a fishing boat hull, adding flotation to a personal watercraft, or insulating live wells and fish boxes, Hi Bond's two-part urethane foam systems deliver consistent, reliable performance that marine applications demand.
