TRUE COMPOSITES Liquid Urethane Pour Foam Base-2 Part Closed Cell Rigid Pour Foam-4 lb Density-Fast-Acting Formula-Boat Buoyancy, Flotation, Filling, Soundproofing & Insulation-1/2 Gallon Kit

• ✅ High-Strength & Durable: TThis two-part liquid pour-foam component system produces foam when Parts A and B are mixed together. It does not contain any CFC blowing agents and has a closed-cell structure that resists water absorption for many years. Once cured, the urethane flotation foam stays intact against solvents, oil, gasoline, fresh or salt water, and features a 95%–98% closed-cell structure with a 4-lb density.
• ✅ Easy to Mix & Apply: Pour Foam Series systems make mixing by hand or machine easy and produce a uniform product with outstanding cell structure. Just mix at a simple 1:1 ratio to ensure even distribution and the strongest foam possible. This fast-acting formula allows about twenty seconds for mixing and pouring, and the foam sets in place within 10 minutes. It’s fully cured and ready for use in just a few hours.
• ✅ Excellent Insulation & Soundproofing: The high-density foam protects boat pipes in colder temperatures and blocks sound, making it ideal for filling dock floats or boat parts for soundproofing and insulation.
• ✅ Various Applications: Ideal for casting, carving, sculpture, plug making, sign making, flotation for boats and buoys, floating decoys, part fabrication, replicating wooden parts, rigidifying, structural support and more.
• ✅ Versatile & Adaptable: This 2-part liquid pour-foam system can be poured in multiple layers with excellent bonding between them. Once fully cured, the foam can be coated with polyester, epoxy, or vinyl ester resins without melting. Shaping is easy once cured.

4lb. density urethane flotation foam is ideal for marine applications such as soundproofing, insulating, filling voids, and adding buoyancy. This two part expanding foam fills cavities and can be shaped to form to keep your boat or dock floating. Foam cures to a rigid form containing 95 to 98% closed cell structure so it is unaffected by gasoline, oil, fresh or salt water, or solvents. Even after prolonged exposure, our flotation foam maintains buoyancy. Mix at a 1:1 resin to hardener ratio to ensure equal, even distribution and the strongest possible foam. This fast acting formula allows approximately twenty seconds for mixing and pouring, as foam will be set in place within 10 minutes. It's ready for use in just hours. 4 lb foam has a flotation range of 100-120 lbs per quart. 4 lb foam expansion: A 1/2 Gallon Kit expands to approximately 1 cubic feet; A 2-Gallon Kit expands to approximately 4 cubic feet. All expansion rates and times given are temperature critical. Temperatures below 75 degrees F will lower the expansion rate therefore requiring more foam. Ideal working temperature is 75 to 80 degrees F or above. Accurate measuring is critical. Once fully cured, it can be laminated over with any type of polyester, epoxy or vinyl ester resin without melting
