Product Details

Mix TotalBoat 2-Part Polyurethane Flotation Foam in equal parts and pour in place to soundproof, insulate, provide buoyancy, and even create art. Pourable foam has 94% closed-cell structure to resist absorbing water, and is unaffected by gas or oil. Available in 2 lb & 6 lb density.

2 pound density foam is great for filling voids in non-structural applications. Can be poured beneath decks and inside cavities to provide buoyancy, and has a flotation range of 75 lbs/qt and 300 lbs/gal.

6 pound density foam has higher compressive strength, ideal for filling cavities to support heavy loads. Its smaller cell structure makes it a popular choice for uses ranging from buoys to sculptures. Its flotation range is 23 lbs/qt and 92 lbs/gal.

Both have been tested in accordance with U.S. Coast Guard Regulation # 33 CFR 183.114.

Available in 2-Quart and 2-Gallon Kits.

Instructions

2-Part Polyurethane Flotation Foam Specifications:
  • The lightweight, 2 lb. density foam is commonly used for filling voids, filling under decks, and practically any other flotation or insulation application.
  • 6 lb. density foam is used for architectural castings, support applications, and has virtually an unlimited number of potential uses.
  • The densities shown refer to the weight per cubic foot of expanded foam (12 in. x 12 in. x 12 in.)
  • 2 lb. density foam expansion: One 2-Quart Kit expands to approximately 2 cubic ft.; one 2-Gallon Kit expands to approximately 8 cubic ft.
  • 6 lb. density foam expansion: One 2-Quart Kit expands to approximately 3/4 cubic ft.; one 2-Gallon Kit expands to approximately 3 cubic ft.
  • All expansion rates and times given are temperature critical. Temperatures below 75 degrees F will lower the expansion rate, which will require more foam. The ideal working temperature is 75 to 80 degrees F, or higher.
  • Accurate measuring of these products is extremely critical.
  • Once fully cured, either foam can be laminated over with any type of polyester, epoxy, or vinyl ester resin without melting. Polyurethane foam is compatible with both epoxy and polyester resin systems.
  • This product can be poured in multiple layers, with excellent bonding between layers.
  • Working time before foaming: Approximately 45 seconds (2 lb. density) to 65 seconds (6 lb. density).
  • Time before full expansion: Approximately 5 minutes
