Solids content

The solids content of a solution (stain, lacquer, etc.). The solids content is what is left behind (solids residue) after a solvent has evaporated. The dry lacquer film on the surface is referred to as the coat strength or thickness and given in. For example, NC lacquers have a mean solids content of 25%, meaning 75% of the applied materials are solvents and diluents that evaporate. The solids content is the ratio of backweighing and weighing after the solvent has evaporated due to the effect of heat (60°C to 120°C) expressed as a percentage.
