WET PAINT ANALYSIS


DENSITY

Mass per unit volume of a material at a specified temperature.

Standards

Significance:

If density is not within spec, then there is a good chance that there could be some error in charging of the batch.

Non Volatile Matter

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.

Standards

Significance:

Volume Solids

Defined as the total volume of non-volatile solids present in one litre of paint.

Standards

Significance:

International Standard BS 5493

Bresle Test

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

Standards

Wet Film Thickness
