In one aspect, a gypsum panel includes a gypsum core, a fiberglass mat, and a wetting agent deposited across an entire thickness of the fiberglass mat. The wetting agent is deposited onto the first fiberglass mat in an uncoated state of the fiberglass mat such that the wetting agent penetrates the entire thickness of the fiberglass mat.

Coating compositions are provided that eject droplets of condensed fluid from a surface. The coatings include a nanostructured coating layer and in some embodiments, also include a hydrophobic layer deposited thereon. The coating materials eject droplets from the surface in the presence of non-condensing gases such as air and may be deployed under conditions of supersaturation of the condensed fluid to be ejected. A heat exchanger design utilizing the coating is described herein.
