Morphology

antifouling = fouling (semi-transparent) = anti + foul + ing

The immediate base is fouling, and adding anti- straightforwardly yields 'preventing fouling'.

Etymology

Antifouling comes from anti- 'against' and foul 'to make dirty'. So an antifouling is the paint or method that keeps barnacles and algae from sticking to a boat's hull.
