4lb Boat Pour Foam Kit, 4 Gallon | Closed-cell foam for flotation, buoyancy, insulation & filling

Exceptional Strength: This two-part liquid pour-foam system creates foam when Parts A and B are combined. It contains no CFC blowing agents and has a closed-cell structure that resists water absorption for years. Once cured, the urethane flotation foam remains intact against solvents, oil, gasoline, fresh or salt water, and benefits from a 95%98% closed-cell structure with a 4-lb density. Easy to Mix and Use: Pour Foam Series systems make hand or machine mixing simple and produce a uniform product with an excellent cell structure. Just mix at a 1:1 ratio for even distribution and the strongest possible foam. This fast-acting formula allows about twenty seconds for mixing and pouring, and the foam sets within 10 minutes. Fully cured and ready for use in just a few hours. Ideal Expanding Foam for Insulation: The high-density foam protects boat pipes in colder temperatures and blocks sound, making it perfect for filling dock floats or boat parts for soundproofing and insulation. Versatile: Excellent 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. 2-Part Liquid Pour Foam Component System: This product can be poured in multiple layers with strong bonding between layers. Once fully cured, the foam can be coated with polyester, epoxy, or vinyl ester resins without melting. Shaping is simple once cured
