scope:

This specification covers a complete coal tar epoxy polyamide black (or dark red) painting system for the protection of steel surfaces that will be exposed to severely corrosive conditions.

This system is suitable for use on parts or structures exposed in Environmental Zones 2A (frequently wet by fresh water), 2B (frequently wet by salt water), 2C (fresh water immersion), 2D (salt water immersion), 3A (chemical, acidic), 3B (chemical, neutral), and 3C (chemical, alkaline). Its resistance to chemical fumes, mists, and splashings is generally considered to be good, but its suitability for prolonged immersion in specific chemicals should be confirmed by trial tests in the absence of applicable case histories. It is also suitable for underground exposure and as a protective coating for sound concrete surfaces in marine and some chemical environments.

Its good weathering properties can be improved by applying a finish coat of a compatible aluminum pigmented paint.

Although it is self-priming and exhibits good adhesion to clean structural steel surfaces, it may also be used over suitable inhibitive primers.

The color of paint is black unless red is specified.
