Abstract
An overcoat that imparts a superhydrophobic surface to a painted surface of an object is a suspension of hydrophobic particles in a polymeric binder and a plasticizer in a solvent or mixed solvent. The particles are a metal oxide that is surface functionalized with a fluorinated alkyl silane or an alkyl silane. Surfaces coated using this paint display contact angles in excess of 150° and resist abrasion while retaining superhydrophobicity.
