Epoxy resin paints, inferior to chlorinated rubber for resistance to strong acids, are excellent for dilute acids and strong alkalis. They produce a harder, more abrasion-resistant coating than does chlorinated rubber and are much better for resistance to fats, oils and many organic solvents. Table 3.50 gives data on the chemical resistance of epoxy resin coatings to different materials. 

A wide range of paints and other organic coatings is used for the protection of mild steel structures. Paints are used mainly for protection from atmospheric corrosion. Special chemically resistant paints have been developed for use on chemical process equipment. Chlorinated rubber paints and epoxy-based paints are used. In the application of paints and other coatings, good surface preparation is essential to ensure good adhesion of the paint film or coating. 

Organic coatings may vary from very dense to rather open for water vapour. A dense coating (ideally without flaws), based on epoxy, polyurethane or chlorinated rubber polymers, may block ingress of aggressive species. Nevertheless, the presence of such a layer strongly hinders the evaporation of the moisture that is present in the concrete at the time of treatment. This situation can lead to loss of adhesion to the concrete and thus to a loss of effectiveness of the coating. 

Chlorobenzene [108-90-7] is a colorless, neutral liquid with a weak, benzene-like odor. It is insoluble in water and miscible with organic solvents. Chlorobenzene has a good solvency for fats, oils, resins, polymers, binders, rubber, and chlorinated rubber. Cellulose ethers dissolve in the presence of small amounts of alcohols cellulose nitrate is insoluble. Chlorobenzene is a solvent in the production of bitumen and asphalt coatings for building protection. 

Zinc-rich coatings can be classified as organic or inorganic. The organic zinc-riches have organic binders, with polyamide epoxies and chlorinated rubber binders being the most common. Other types such as urethane zinc-rich are also available. These latter coatings are more easily applied than the other zinc-rich... 

Zinc-rich coatings are subdivided as organic or inorganic. The organic zinc-rich coatings have organic binders such as polamide epoxies, chlorinated rubber binders, and urethane binders. 

Because the film is formed by precipitation, chlorinated rubber coatings are very vulnerable to attack by the solvents used in their formulation and have poor resistance to nearly aU other solvents. They are also vulnerable to attach by organic carboxyhc acids, such as acetic and formic acids [19].
