Abstract: An electronic device may have input-output devices such as keyboard keys or other buttons. Components such as cameras and other devices may have trim structures. A housing may be used to form an enclosure for the components. Keyboard keys, trim structures, and/or other device structures such as housing structures may be provided with wear-resistant coatings. For example, a keyboard key may have a glyph such as an alphanumeric character formed from patterned layers of ink. To prevent wear to the key and glyph, the glyph may be coated with a wear-resistant coating. The wear-resistant coating may be formed from a polymer with embedded mineral particles such as aluminosilicate particles.
