Marine Grade Buoyancy Foam
2 part expanding buoyancy foam 2 Lb US Coast Guard Approved. Available in kits from 2 gallons and up. Drum kits available.
This two-part liquid, expanding rigid urethane foam is a closed cell,
pourable foam, which resists the absorption of water.
The densities shown refer to the weight per cubic foot
of expanded foam (1728 cubic inches).
Once fully cured this foam can be laminated over with epoxy resin.
This product can be poured in layers with excellent bonding between the layers.
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 temp. is
75 to 80 degrees F or above.
Accurate measuring of these products is critical.
Find our selection of measuring containers here.
Working time before foaming: approx. 45 seconds
Time before full expansion: approx. 5 minutes
The lightweight foam is commonly used for filling voids, filling
under decks and other flotation or insulation applications.
Higher densities are used for architectural castings, support applications
and has a virtually unlimited number of uses.
