Anti dripping coatings for hoods

A kitchen exhaust appliance comprising:

• a body having a plurality of external surface panels and defining an exhaust vent therethrough;
• and
• an anti-dripping coating applied to at least one external surface panel of the plurality of external surface panels, the anti-dripping coating is formulated from a solvent and a precursor, the solvent being alcohol, water, benzene, an organic solvent, an inorganic solvent, a halogenated solvent or a combination thereof, and the precursor being cyclosilazanes, di-Me, Me hydrogen, polymers with di-Me, Me hydrogen silazanes, reaction products with 3-(triethoxysilyl)-1-propanamine, hydrocarbons, C9-C11 n-alkanes, isoalkanes, cyclics, aromatic compounds, silicone-nitride-oxygen network precursors, polysiloxane precursors, fluorocarbon precursors, nonpolar materials, di-n-butyl ether, or combinations thereof,
• wherein, upon application to the at least one external surface panel, the anti-dripping coating forms a surface having a water contact angle of at least 70 degrees thereon and a surface energy of less than less than 35 mN/m.
