The antifouling agent comprises a structure comprising a central aluminum atom bound to an Rl group, bound to an R2 group, and bound to an R3 group. One or more of the chemical groups Rl, R2, and R3 are antifouling groups comprising the struc - ture -O((CH 2) .0) .R4, where n is an integer from 1 to 20, m is an integer from 1 to 100, and R4 is a hydrocarbyl group. The chem- ical groups Rl, R2, or R3 that do not comprise the antifouling group, if any, are hydrocarbyl groups.
