The redesigned MPI 500 Series defines verified standards for coatings that protect fuel and waterfront steel assets.
Developed in collaboration with industry experts and the U.S.
Department of War (DoW), the MPI 500 Series Standards establish
consistent product performance testing criteria for coatings used on
industrial infrastructure assets, such as steel pilings and waterfront
structures, interiors and exteriors of fuel pipelines, and petrochemical
storage tanks.
Each standard includes detailed instructions for performance criteria,
surface preparation, and testing protocols.
Purchase and download the Standards from the MPI Store.
Each MPI 500 Standard defines a suite of product performance testing for coatings intended for industrial and Department of War (DoW) applications. Purchase the standards to gain access to precise performance criteria and testing methods.

Standard Name
Description
MPI 500
See Approved ProductsEpoxy, Interior Steel Fuel Tank Coating
A two-component, pigmented, epoxy coating for protecting interior steel surfaces used for the transportation and storage of fuels. Intended as the basecoat to a two-coat system of MPI 500 and MPI 501 or a three-coat system of MPI 500, MPI 501, and MPI 503.
MPI 501
See Approved ProductsEpoxy, Interior Steel Fuel Tank Coating
A two-component, pigmented, epoxy midcoat for interior and exterior steel surfaces used for the transportation and storage of fuels. Intended as the topcoat to a two-coat system of MPI 500 and MPI 501 or mid-coat of a three-coat system of MPI 500, MPI 501, and MPI 503.
MPI 502
Zinc-Rich Epoxy Primer, for Industrial Steel Structures
A 2 or 3 component, solvent-based epoxy zinc-rich primer intended for use on properly prepared ferrous metal surfaces. Also suitable for direct application to properly prepared galvanized metal surfaces. May be exposed without a topcoat, or may be subsequently top coated with 2 component epoxy or polyurethane coatings or both.
MPI 503
Epoxy, Interior Steel Fuel Tank Coating
A two-component, pigmented, epoxy topcoat for interior steel surfaces used for the transportation and storage of fuels. Intended as the topcoat to a three-coat system of MPI 500, MPI 501 and MPI 503 (this standard).
MPI 504
Polyurethane Topcoat, Two-Component, Pigmented, Gloss
A two-component pigmented, solvent borne polyurethane intended for use on exterior steel fuel tanks. The coating is intended as the topcoat to a three coat system of MPI 502 Primer, MPI 501 Epoxy Midcoat, and MPI 504 (this standard).
Low VOC, Flexible, High Adhesion Coating
A low VOC, flexible, high adhesion, coating for protecting steel petroleum fuel tank interior structures. Related to MPI 506.
MPI 506
Low VOC, Flexible, High Adhesion, Epoxy, Coating
A two-component low VOC, flexible, high adhesion, poxy coating for protecting steel and concrete petroleum fuel tank interior structures. Related to MPI 505
MPI 510
See Approved ProductsLow VOC, Self-Priming, Splash Zone Coating (SZC)
A self-priming a coating for protecting new or existing steel sheet piling and other steel waterfront structures such as under pier petroleum, oil, and lubricant (POL) utilities.
Marine Atmospheric Exposure, Full System
A systems standard consisting of a two-component fluoropolyurethane topcoat applied over a two-component non-zinc flexible epoxy barrier coating for protecting new or existing exterior steel structures under atmospheric exposure.
Splash zones and atmospheric steel exposed to harsh marine environments are among the most demanding performance challenges a coating can face. Join MPI’s Terrance Mayes to learn why NAVFAC requested MPI Industrial Standards 510 and MPI 515, what factors influenced new performance expectations, and where these standards are being adopted beyond U.S. Naval facilities.
The MPI 500 Series gives manufacturers a clear path to verified
performance and DoD project eligibility. Test your coatings through
MPI’s testing and listing program to earn placement on the Approved
Products List (APL) and access new markets.
