Coatings applied to a vehicle after its construction and initial painting: may be applied in car plants to repair damage, but is more usually applied in body shops to repair damage or change appearance.
The ability of a liquid coating to resist forces causing them to flow. Water has a relatively low viscosity, whilst some resins such as pitch are very viscous. Viscous coatings will resist forces such as brushes or rollers used to apply them. Viscosity usually reduces as temperature rises, so some coatings (such as powder coatings) only become liquids as high temperatures. If the viscosity is too low, however, the coating may not stay on the substrate at the correct thickness and evenness, so a balance is required.
Volatile organic compounds are any organic liquid and/or solid that evaporates spontaneously at the prevailing temperature and pressure of the atmosphere with which it is in contact. VOCs can contribute to poor air quality by raising ozone concentrations at ground level in certain climatic conditions.
Percentage of coating that evaporates.
