PMMA itself is actually hydrophobic but its very common to add rubberizing agents because the material is also brittle, making what we buy as Plexiglass or other commercial brands hydrophillic. Lexan is hydrophobic and less brittle than Plexi, so I'm guessing its unmodified and the end product is more or less just Lexan and shouldn't bow or bend at all if one side is exposed to water. How much does Plexiglass bow?
