What is the major role of solvents in paint?

The major role of solvents in paint is to keep the paint in a liquid form for application. Solvents are crucial in adjusting the viscosity and flow of paint, making it easier to apply. They enable the paint to spread uniformly over surfaces, allowing for smooth application with various tools, such as brushes or rollers. After application, the solvents evaporate, leading to the formation of a solid film that adheres well to the substrate. This ability to maintain a liquid state during application is essential for achieving the desired finish and coverage.

While the other functions of paint, such as providing color, enhancing adhesion, and improving texture, are also important, they are not the primary role of solvents. Solvents primarily serve as carriers for the pigments and resins in the paint, facilitating proper mixing and application before evaporation and film formation occur.
