hydrophobic does not mean something floats. floating is determined by a difference in density. Hydrophobia, on the other hand, is the tendency of a molecule to be attracted to the water. a good example is a lava lamp. sometimes the wax/oil is hot and floats to the top, sometimes it is cooler and goes back to the bottom, but it is always hydrophobic. That hydrophobia is why it clumps together in balls.

density (of the liquid resin, we probably don't care so much about the cured) is what matters. It's probably not too dense, but it would be better to ask and know for sure, then waste money on disappointment.
