This standard covers a cold-applied coal-tar coating for use on underground and underwater steel structures.
INTENDED USE: This coating, when applied over properly prepared carbon steel, 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), 3B (chemical exposure neutral), and 3C (chemical exposure alkaline). The coating is also suitable for use on hydraulic structures and pipe. It must be used with discretion for immersion in corrosive chemicals since the coating is dissolved by some organic solvents and attacked by oxidizing solutions.
This coating is intended for application by brush or spray for use by itself or as a primer in a multi-coat system.
