Water absorption <= 0.06 lbs/sq ft

Looks PU expanding foam has the ability to absorb water too, although I haven't looked at converting any numbers to percentages.
I haven't looked at the buoyancy numbers in detail but I don't think the epoxy foam is as buoyant as the PU foam.

I was only interested in it due to the slower expansion rate, but if it's not as buoyant I won't be using it.

They do make the statement that it could be used where you would use foam core or honeycomb.

The dude in the video wants to use it in his rudder, where the buoyancy would not necessarily be desirable anyway
