wettability
Liquid spreading tendency
Wettability is a material's ability to maintain contact with a liquid, determined by how the liquid spreads across or beads up on its surface.
High wettability means liquids spread easily; low wettability means they bead and roll off.
The property matters in engineering, geology, and materials science: The coating's wettability affects how paint adheres, oil recovery depends on the wettability of reservoir rock.
