Organic Protective Coatings

Many paints, coatings and high performance organic coatings have been developed as a need to protect equipment from environmental damage. Of prime importance in the development of protective coatings was the petroleum industry that produced most of the basic ingredients from which most synthetic resins were developed. (coating costs) The cracking of petroleum produced a multitude of unsaturated workable compounds that are important in the building of large resin polymers such as vinyls and acrylics. The solvents necessary for the solution of the resins were also derived from petroleum or natural gas. The building blocks for epoxies and modern polyurethane coatings are other derivatives produced by refining petroleum products. Some importantconcepts for designing corrosion resistant coatings are:


According to the U.S. Department of Commerce Census Bureau, the total amount of organic coating material sold in the United States in 1997 was 5.56 billion L(1.47 billion gal), at a value of $16.56 billion. The total sales can be broken down into architectural coatings, product original equipment manufacturers (OEM) coatings, special-purpose coatings, and miscellaneous paint products. A portion of each of these was classified as corrosion coatings for 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 billionto $167.5 billion. (reference)
