Protective Coatings Application: Volume Solids

Objective: To recognize that paints and coatings are liquid materials composed of volatile and non-volatile components.

  • The percentage of volume solids expresses how much of the coating is considered non-volatile and will remain on the substrate after the volatile portion has evaporated.
  • All coatings have a defined volume solids content.
  • Volume solids is found on product data sheets.
  • Volume solids is required to calculate the wet film thickness and spreading rate.
