MIL-PRF-23236 Coating Systems For Ship StructuresThis specification covers four types of air pollution regulated ship and structure coatings that comply with the National Emission Standards for Hazardous Air Pollutants \(NESHAP\) for shipbuilding for state and federal regulations. There are nine classes of coating systems. There are four grades of coating systems based on temperature of application and cure. In addition to tanks, all paint systems qualified to this specification are suitable for use on any ship structures, interior or exterior, for corrosion control. Except for trace levels, all types are free of lead, chromium, cadmium, and asbestos \(see 3.2.3\). All types have levels of hazardous air pollutants \(HAPs\) that do not exceed applicable NESHAP levels \(see 3.2.2.2\). Dry Type V, VI, VII, and VIII coating residues and debris are non-hazardous waste under U.S. Environmental Protection Agency \(USEPA\) regulations in effect on the date of this specification. Type VII coating will not have any solvent added to either the base resin component or the hardener component.

6.6 Definitions. Interpretation of the meaning of coating related terms in this specification are to be consistent

with the Coatings Encyclopedic Dictionary, Federation of Societies for Coating Technology, 492 Norristown Road,

Blue Bell, PA 19422-2350. A limited number of definitions are given below.

6.6.1 Coating components (except Types VIII and VIIIa). Coating components are individually packaged

components such as base component (part A) and converter component or hardener (part B).

6.6.2 Coating. A coating is the resin component (base) and converter mixed and ready for application.

6.6.3 Coat. A coat is a single application of the coating which may be composed of multiple passes by

application equipment.

6.6.4 Coating system. A coating system is the total number of coats as specified by the manufacturer at the

time of qualification testing and at the dry film thickness per coat as specified by the manufacturer at the time of

qualification testing.

6.6.5 MOGAS. MOGAS is motor vehicle gasoline.

6.7 Packaging recommendations. Suggested packaging requirements are contained on table IX.
