Density & Specific Gravity
To maintain consistency of a coating, the Density should remain constant from batch to batch. Density Cups, also known as Specific Gravity Cups or Picnometers, are used to determine the mass per unit volume (Specific Gravity) of a liquid at a given temperature. Specific Gravity is defined as the ratio of the density of a given substance to the density of water, when both are at the same temperature. As the Specific Gravity Cup is an exact measurement of the volume of the liquid, it is imperative that the exact weight of the sample is obtained.

Density
The density of paint will depend on their ingredients in the paint. Density is also known as specific gravity or mass per unit volume.The more ingredients/particles in paint the more mass per unit of volume. This is called density (S.G) can be written as g/cm3. The reference substance for liquids is nearly always water. It is important to specify temperature for both the sample and reference. To find the density of a paint you need to establish the weight of the product. For these several instruments are available, pyknometers, immersion bodies, densimeters and weighing scales.
