Mass per unit volume of a material at a specified temperature.
If density is not within spec, then there is a good chance that there could be some error in charging of the batch.
The volume of the dried coating divided by the volume of liquid coating, multiplied by 100, provides the volume percent non-volatile matter inthe total liquid coating.
Defined as the total volume of non-volatile solids present in one litre of paint.
Viscosity is the force per unit area that resists the flow of two parallel fluid layers.

International Standards: ISO 8502-6 and ISO 8502-9 Contaminating the surface prior to the coating application due to salts such as chlorides and sulphates
Dete rmined as being between the clearance of the deepest notch face wetted and the clearance of the next deeper notch face not wetted by the film.
The wet-film thickness is determind as being between the clearance of the deepest notch face wetted and the clearance of the next deeper notch face not wetted by the film.
