The paint manufacturing industry produces a variety of products. These products are used to protect, preserve and beautify the objects to which they are applied. In general, paints are classified by their proposed function or service applications such as architectural coatings, industrial coatings, special purpose coatings, varnishes, lacquers, etc. The characteristics of most important classes are summarized below. 

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 x 10 L, 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, with approximately one third of the total sales for the main purpose of corrosion protection [1].

The major coatings markets in the United States consist of architectural coatings (consumer and decorative), product finishes (maintenance/protective coatings for bridges, industrial machinery, etc.), special purpose coatings such as automotive finishes (DEM and refinish), and miscellaneous allied paint products (e.g., for appliances, containers, and forniture and related materials) (Table 27.2). 

Ethylene oxide (qv), propylene oxide (qv), butylene oxide, and other epoxides react with ethanol to give a variety of Uquid, viscous, semiwax, and soUd products. These products are used ia the coatings iadustry as solvents, and as paints, antioxidants, corrosion inhibitors, and special-purpose polymers. Recent concerns about the health effects of ethanol containing glycol ethers have led to the decline in the production of these compounds. 

Organic pigments are used to color a variety of media. It is useful to distinguish between three primary fields of application the coatings and paints industry, the printing inks industry, and the plastics and fibers industry. Besides, organic pigments are used for special purposes, for instance in office materials and in the mass coloration of paper. 

P.V.23, also referred to as Carbazole Violet, is a universally useful product. Its color, a bluish violet shade, is not accessible with other Pigments. P.V.23 is used in almost all media which are typically colored with pigments. The list of suitable systems ranges from coatings and paints to plastics, printing inks, and other special-purpose media. P.V.23 is entirely fast to many organic solvents. At standardized conditions (Sec. 1.6.2.1), it is fast to alcohols, esters, and aliphatic hydrocarbons as well as to plasticizers such as dibutyl and dioctyl phthalate. Other solvents, such as ketones, are colored slightly (step 4). 

Polyurethanes are addition polymers containing the urethane linkage,-RNHCOOR -. They have been of great commercial importance for 50 years, with many applications as foam (furniture and automotive seating, insulation, carpet underlay), coatings (automotive and architectural paint), adhesives and sealants, and as elastomers for a variety of special purposes. 

A special type of paints used on ships is called antifouhng coatings and actually the purpose here is to develop paints where fouling does not adhere on the ships surface. While the paint itself should of course have good...
