What is the main purpose of solvents in painting?

The main purpose of solvents in painting is to dissolve or suspend paint constituents. Solvents serve as a carrier for the pigments and binders in paint, allowing these components to be evenly mixed and effectively applied. By dissolving or suspending these materials, solvents ensure that the paint maintains a workable consistency and adheres properly to the surface being painted. Additionally, as the paint dries, the solvent evaporates, leaving behind the solid components that form a durable film.

While solvents may indirectly influence color, texture, and adhesion, their primary and most significant role is to facilitate the application process by enabling an even distribution of the paint's components. This is essential for achieving the desired finish and ensuring that the paint performs well once it has dried.
