The invention provides a highly durable surface coating intended to inhibit the formation of ice at sub-0 C. temperatures as well as reduce the accumulation of dirt and insect debris to a vehicle surface upon impact. A continuous, durable matrix surrounds both low-surface-energy (low-adhesion) material inclusions as well as hygroscopic material inclusions. Some variations provide a low-friction, low-adhesion material comprising: a durable continuous matrix; a plurality of first inclusions, dispersed within the matrix, each comprising a low-surface-energy polymer; and a plurality of second inclusions, dispersed within the matrix, each comprising a hygroscopic material. The matrix and the first and second inclusions form a lubricating surface layer in the presence of humidity. Other variations employ a durable continuous matrix and a plurality of inclusions, dispersed within the matrix, each comprising a low-surface-energy polymer surrounding a hygroscopic material. Coating precursors and methods of forming final coatings are also described.

A stain resistant, soft touch coating composition can include: (a) a fluoropolymer comprising at least one reactive functional group; (b) a polyester polyol; and (c) a crosslinker reactive with (a) and (b). The polyester polyol can include a reaction product obtained from a mixture of reactants including: an aliphatic diol; a polyol having 3 or more hydroxyl groups; and a cyclic polycarboxylic acid, or an anhydride or ester thereof.

A sterilization method including exposing a coating film of a coated article to hydrogen peroxide under a condition employed for a sterilization method using hydrogen peroxide; where the coating film is used on a surface of the coated article to be exposed to hydrogen peroxide, and includes a fluorine atom and a urethane bond; and where the coated article is an interior material of a factory for producing a food or pharmaceutical product, an interior material of an experimental building, or an exterior material of devices used in these factories or buildings.
