Most manufacturers of these lining systems provide training programs for plant maintenance personnel. The physical properties and the chemical resistance of ambient-cured synthetic resin lining systems are shown in Tables VI and VII, respectively. The tables shown above all provide the design and corrosion engineer with basic information on the various lining systems discussed. They identify specific cor- rosives encountered in various metal-finishing operations. Enumerated are each of the various types of linings and a general recommendation for its use in the par- ticular medium. It is recommended that the acceptability of specific linings, in specific media, be verified with the manufacturer. Chemical-Resistant Brick and Tile Linings Table VII.
