Pigment covering power measured by paint consumption

The method for measuring the hiding power of paint can be divided into: 

(1) The method based on the determination of the minimum weight of paint required to cover the surface of the unit and

(2) The method is based on the determination of the minimum thickness of the paint layer when the paint shades the colored bottom surface,

The thickness of the paint layer determines the covering power, and the consumption amount on the surface of the color depth covering unit should be expressed by another term "economic effect".                  

There is a difference in theory between these two concepts, but in practice, from the point of view of measuring the actual consumption of color paint on the unit surface, that is, from the point of view of economic effect, the selection power also has a certain effect. very important meaning.

If the result of measuring the hiding power according to the thickness of the paint layer is converted into the consumption of pigment on the unit surface, then the concept of selecting the hiding power measured by the thickness of the color-connected paint layer is related to the consumption of paint on the unit surface. The concept of coverage between the two disappears, and the determination of covering power must always be carried out under completely defined conditions. (Related instrument: hiding power paper)
