Definition - What does Vehicle Solid mean?

A vehicle solid is the portion of nonvolatile solid matter contained in the vehicle of a paint or coating. In other words, it is the portion of the film that remains on the coated surface after drying is complete. Vehicle solids may be expressed as a percentage of the total paint vehicle, or it can be expressed in terms of overall weight or volume. A vehicle solid is an important component of protective coatings used to prevent corrosion.

A vehicle solid is also known as a resin solid.

Corrosionpedia explains Vehicle Solid

All paints and coatings are comprised of both solid and liquid components. Both of these components can be further classified as volatile and nonvolatile. The volatile elements evaporate once the coating is applied, leaving the nonvolatile components behind.

The nonvolatile matter that remains to form the final coating on the surface is the vehicle solid component. This solid matter consists of different elements, such as pigments, binders and other compounds necessary for the coating film. The vehicle solid compounds also dictate various properties of the final coating, such as adhesion, durability, flexibility and gloss.
