2-Part Polyurethane Marine Flotation Foam
Description TotalBoat Marine Flotation Foam is great for filling voids, especially under decks. It’s thermal and sound-proofing abilities make it ideal for a number of other insulation and flotation applications. 94% closed-cell foam structure lets it maintains buoyant pressure even after prolonged exposure to water. This 2 part pour-in-place expanding polyurethane boat foam reaches full expansion in about five minutes, and can be poured in multiple layers with excellent bonding between layers. The cured foam hardens into shape with minimal shrinkage, is not affected by gas or oil, and resists mold and mildew. Once fully cured, foam can be laminated over with polyester, epoxy, or vinyl ester resins. Density: Available in 2 lb. or 6 lb. density foam. The densities refer to the weight per cubic foot (12″ x 12″ x 12″) of expanded foam Size: 2-Quart Kit and 2-Gallon Kit Color: Brown transparent liquid (resin and activator) Expansion rate: Flotation foam begins expanding 10-20 seconds after mixing, and will continue to expand for about 5 minutes (in 70-80°F conditions) Compliance: Both foam densities have been tested in accordance with the USCG Regulation #33 CFR 183.114. Note: Continuous water submersion can eventually lead to loss of buoyancy over a period of years. Storage: 33-95°F – DO NOT ALLOW TO FREEZE Uses for 2 lb. Density Boat Flotation Foam Lightweight foam is perfect for filling non-structural voids Pour beneath decks and inside cavities to provide buoyancy 2 lb. Density Flotation Boat Foam Specifications Components: 2 (Resin and Activator) Application temperature: 60-85°F or above (75-80°F is optimal for yield and cure/working times) Volume: The 2-quart kit expands to approximately 2 cubic ft.; the 2-gallon kit expands to approximately 8 cubic ft. Compressive strength: 38 psi Mix ratio by volume: 1 to 1 Mix ratio by weight: 100:109 Cream time: 45 seconds Gel time: 235 seconds Tack-free time: 380 seconds Rise time: 400 seconds Flotation range (admixed): 75 lbs/qt and 300 lbs/gal For nonstructural applications only Note: Accurate measuring of resin and activator is extremely critical. All expansion rates and times listed are dependent on temperature. Temperatures below 75°F will lower the expansion rate, which will require more flotation foam. Uses for 6 lb. Density Flotation Foam Higher compressive strength is great for filling cavities to support heavy loads Flotation for buoys Creating sculptures and other works of art 6 lb. Density Flotation Foam Specifications Components: 2 (Resin and Activator) Application temperature: 60-85°F or above (75-80°F is optimal for yield and cure/working times) Volume: The 2-quart kit expands to approximately 3/4 cubic ft.; the 2-gallon kit expands to approximately 3 cubic ft. Shear strength: 220 psi Compressive strength: 55-80 psi Tensile strength: 500 psi Mix ratio by volume: 1 to 1 Mix ratio by weight: 1 to 1 Cream time: 65 seconds Gel time: 150 seconds Tack-free time: 215 seconds Rise time: 200-250 seconds Maximum service temperature: 200°F Flotation range (admixed): 23 lbs/qt and 92 lbs/gal Note: Accurate measuring of resin and activator is extremely critical. All expansion rates and times listed are dependent on temperature. Temperatures below 75°F will lower the expansion rate, which will require more flotation foam. WARNING: The 6 LB. Density Flotation Foam Activator can expose you to chemicals including ethylene glycol, which is known to the State of California to cause birth defects or other reproductive harm.
