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
- ✅ High-Strength & Durable: This two part liquid pour foam component system produces foam when mixing part A and B together. It does not contain any CFC blowing agent and has a closed-cell structure that allows it to resist water absorption for many years. Once cured, the urethane flotation foam remains stable against solvents, oil, gasoline, fresh or saltwater, or solvents and features 95%-98% closedcell structure with a 4-lb density!
- ✅ Easy to Mix & Apply: Pour Foam series systems offer ease of mixing by hand or machine and produce a uniform product with exceptional cell structure. Just mix at a 1:1 ratio to ensure equal, even distribution and the strongest possible foam. This fast acting formula permits 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.
- ✅ Excellent Insulation & Soundproofing: The high density foam can protect the pipes on a boat in colder temperatures and block sounds, ideal to fill dock floats or boat parts for soundproofing and insulating!
- ✅ Various Applications: Great 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: 2-Part Liquid Pour Foam Component System can be poured in multiple layers with superb bonding between layers. Once fully cured, foam can be coated with polyester, epoxy, or vinylester resins, without melting. Shaping is simple once cured.
