Economic Comparison Standard of Industrial Protective Coatings

ISO2811-1974 "Paints and varnishes-Determination of density"

The volume solids of each paint manufacturer used for price comparison should be the data tested in accordance with the above-mentioned standards.

5.
How do coating users compare the economics of various manufacturers' coatings?

Some paint users have also realized that it is not easy to accurately reflect the actual situation based on the theoretical cost declared by the paint manufacturer alone, so they have come up with some methods to compare, such as the paint sample provided by the paint manufacturer for on-site spray testing, recording the paint consumption, Calculate and compare the average dry film thickness and coating area.
This method is complicated to operate, the error is also relatively large, and it is material and time consuming.

In fact, the customer has a better comparison method: that is to test the volume solids and specific gravity of the paint, and entrust an authoritative organization according to the above-mentioned standards.
Then calculate the theoretical cost per square by yourself.
