What binds pigment in paint?

• A. Resin
• B. Water
• C. Oil
• D. Wax

Answer: (A)

The main idea here is the binder in paint, which is responsible for holding pigment particles together and sticking them to the surface to form a durable film. The resin acts as that binder. When paint dries, the resin forms a continuous film that traps the pigment particles and adheres to the substrate, giving the coating its cohesion, adhesion, and durability. Water, by contrast, is just the vehicle that carries the pigments and resin during application; it evaporates away as the film forms. Oil can function as a binder in traditional oil-based paints, but the common term for the film-forming binder in most paints is resin. Wax isn’t the primary binder in standard paints.
