Aluminum Pigmented Epoxy Coating System Materials Specification, Performance Based
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). The specified coating system is intended for application by brush, spray, or roller. Type I is for use over steel surfaces blast cleaned to SSPC-SP 6 or better. 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. For either Type I or Type II, the surface should be prepared in accordance with the manufacturer's written recommendations.
