1. A method, comprising:
- applying an initial composition to a contact surface of a component, the initial composition comprising water at a concentration of greater than 0% and up to about 50% by volume, a paint co-solvent between about 9% by volume and about 10% by volume, and a hardener, wherein the hardener comprises an isocyanate composition, a hardener solvent and a hardener solids content, the isocyanate composition comprising between about 50% by weight and about 80% by weight of the hardener, and wherein the ratio of hardener content to non-hardener content of the initial composition is between about 10 parts and about 20 parts of hardener per 100 parts by weight of non-hardener content; and
drying the initial composition to form a dried coating on the contact surface of the component, the dried coating having a dried layer thickness of between about 28 micrometers and about 73 micrometers.

Abstract
A coating composition for coating at least one contact surface of a component is disclosed as well as methods of coating the component with the coating composition. The component may be, for example, an interior trim part for interiors of motor vehicles. The contact surface contacts at least one other component and on which relative movement occurs. The coating may be a wear-resistant and/or a low-friction coating. The coating may be formed on the component from a paint composition and a hardener composition. When the coating is dry, the coating may have a dried layer thickness of between about 25 micrometers and about 100 micrometers.

13. A method, comprising:
-
mixing a hardener composition with an initial paint composition to form an initial coating composition, the initial coating composition having a ratio of between about 10 parts by weight and about 30 parts by weight of the hardener composition per 100 parts by weight of the initial paint composition, the initial paint composition having a non-zero water content of up to about 60% by weight of the initial paint composition and a paint co-solvent content of between about 9% by weight of the initial paint composition and about 20% by weight of the initial paint composition, and the hardener composition comprising an isocyanate composition, a hardener solvent and a hardener solids content, the isocyanate composition comprising between about 50% by weight and about 80% by weight of the hardener composition; applying the initial coating composition to a component; and drying the initial coating composition to form a coating on the component having a dried layer thickness of between about 25 micrometers and about 100 micrometers. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A method, comprising:
-
applying, to a component, an initial coating composition comprising a mixture of an initial paint composition and a hardener composition at a ratio of between about 10 parts by weight and about 30 parts by weight of the hardener composition per 100 parts by weight of the initial paint composition, the initial paint composition comprising; a water content of up to about 60% by weight of the initial paint composition; a paint resin of between about 35% by weight and about 45% by weight of the initial paint composition; a paint co-solvent of between about 9% by weight and about 20% by weight of the initial paint composition; one or more paint additives the total content of which being between about 1% by weight and about 2% by weight of the initial paint composition; and a total paint solids content of between about 35% by weight and about 65% by weight of the initial paint composition, and the hardener composition comprising; an isocyanate composition of between about 50% by weight and about 80% by weight of the hardener composition; a hardener solvent of between about 10% by weight and about 40% by weight of the hardener composition; and a hardener total solids content of between about 60% by weight and about 85% by weight of the hardener composition, and drying the initial coating composition to form a coating on the component having a dried layer thickness of between about 25 micrometers and about 100 micrometers. - View Dependent Claims (28, 29)
