Marine Grade Buoyancy Foam2 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.
Mixing and pouring this foam is quite easy, see the Tutorial Video We are your Buoyancy Foam Supply Store.
