are added to paint and coatings formulations to dissolve other compounds like pigments
, additives and binders. After the paint is applied on the surface, the solvent evaporates, allowing the resin and pigment to produce a film of paint and to dry quickly. Adding solvents in a paint formulation helps to optimize the whole performance of the system.
Even if almost no solvents are present in the final dried coating due to evaporation, their role is essential in coating formulation. Solvents control the viscosity for the application and can have an important effect on film quality, which is strongly dependent on the solvent's evaporation rate during drying. As a result of this they can affect properties such as film appearance, adhesion, or even corrosion.
