Abstract

The present invention relates to a coated article comprising a partial or complete durable non-fluorinated coating on the surface of an article, wherein the coating comprises 5 to 95% by weight of a hydrophobic compound, and 5 to 95% by weight of a surface effect agent, both based on the total solids weight of the coating, where the hydrophobic compound is selected from a hydrophobic cyclic or acyclic alcohol.
