Material Notes:
In applications where density is critical, the four part SF-22 kit is used. This system utilizes fiber reinforced epoxy macrospheres in combination with the standard microsphere syntactic to provide the lowest density possible in void filling, yielding a greater than 60% increase in buoyancy per cubic foot. In this system, cavities are pre-filled with the ~ 0.625 inch diameter macrospheres, specially fabricated to withstand the operating hydrostatic pressure of the vessel. The liquid syntactic is then injected into the cavities around the macrospheres and allowed to cure at room temperature. The resultant low-density system will provide an average of 42 pounds of buoyancy per cubic foot of void space.
