Based on the calculated Henry´s Law constant (60.5 Pa*m3/mol at 25°C) n-hexyl methacrylate will evaporate moderately from the water surface. In the Mackay Level III model, which takes into account transport and degradation processes, n-HMA, when released to air or water, will predominantly remain in the environmental compartment into which it was released (air: 98.1 %; water: 97.4 %).
