Abstract
Hydrophobic coating compositions are provided as are processes to coat articles with the compositions. Extremely hydrophobic coatings are provided by the compositions. Durable, weatherable and scratch-resistant coatings are provided by compositions comprising a trifluoromethyl-containing component and a hardenable material. Processes are also provided for forming hydrophobic coatings on articles without any substantial loss of fluorocarbon solvent used in the coating composition. Articles are coated on a surface thereof with a hydrophobic coating reactant or reaction product which forms a coating having an exposed surface populated with 30% by area or more terminal trifluoromethyl groups.
