Both
organic and metallic coatings are used to provide protection against
corrosion of metallic substrates. These metallic substrates, mostly
carbon steel, will corrode in the absence of the coating, resulting
in the reduction of the service life of the steel part or component.
The total annual cost for organic and metallic protective coatings
is $108.6 billion.
According to the U.S. Department of Commerce Bureau of Census,
the total amount of organic coating material sold in the United
States in 1997 was 5.56 billion liters (1.47 billion gallons), at
a value or $16.56 billion. The total sales can be broken down into
architectural coatings, product OEM coatings, special purpose coatings,
and miscellaneous paint products. A portion of each of these was
classified as corrosion coatings at a total estimate of $6.7 billion.
It is important to note that raw material cost is only a portion
of a total coating application project, ranging from 4 to 20 percent
of the total cost of application. When applying these percentages
to the raw materials cost, the total annual cost of coating application
ranges from $33.5 billion to $167.5 billion (an average of $100.5
billion).
