What to Do When a Small Part of the Car Paint Chips Off?

[MacFinley]

Car paint chipping off a small part can be resolved by using a touch-up paint pen for coloring treatment, which helps prevent the rust from expanding and worsening. Car paint generally consists of four basic components: film-forming substances (resins), pigments (including extender pigments), solvents, and additives. The film-forming substance is the main component of the paint, serving to keep the pigments bright, making them durable and able to adhere to the surface of the object, and is the substance that determines the type of paint. Pigments are one of the two non-volatile substances in paint, providing color and durability to the topcoat, while also giving the paint its covering power, increasing strength and adhesion, altering gloss, and improving flow and application properties. Solvents are the volatile components in paint, primarily functioning to fully dissolve the resins in the paint film, enabling the paint to be applied normally. Additives include curing agents that accelerate drying and enhance gloss, as well as retarders that slow down the drying speed.
