This specification covers the requirements for an ambient temperature cure, two-component aluminum pigmented epoxy coating that is intended for use as a single or multi-coat system on steel.
Coating systems meeting this specification are suitable for exposures in environmental zones 1A (interior, normally dry), 1B (exterior, normally dry), 2A (frequently wet by fresh water, excluding immersion), 2B (frequently wet by salt water, excluding immersion), and 3B (chemical exposure, neutral). (See Note 13.1.)
The specified coating system is intended for application by brush, spray, or roller. (See Note 13.2). Type I is for use over steel surfaces blast cleaned to SSPC-SP 6 or better. (See Note 13.3.) Type II is for use over non-blast cleaned as well as blast cleaned steel surfaces, i.e., surfaces cleaned to SSPC-SP 2 or better. (See Note 13.4.) For either Type I or Type II, the surface should be prepared in accordance with the manufacturer’s written recommendations.
This coating is typically based on a reactive oxirane (epoxy) functional resin with an amine or polyamide functional curing agent. (See Section 4.)
The principal functional pigment is aluminum paste or flake powder. (See Section 4.)
