unwettable
Water cannot penetrate
Unwettable describes a surface that repels water rather than absorbing it—droplets bead up and roll off instead of spreading or soaking in.
The term appears in materials science and chemistry: The lotus leaf's unwettable surface inspired new fabric coatings.
Wax, oil, and certain synthetic materials create unwettable surfaces.
