(12) "Nonskid coating" means a coating applied to the surfaces of a ship for the purpose of providing slip resistance.

(13) "Nuclear coating" means a protective coating used to seal porous surfaces such as steel or concrete that otherwise would be subject to intrusion by radioactive materials.

(14) "Organic zinc coating" means a coating derived from zinc dust incorporated into an organic binder, that:

(a) Contains more than 8 pounds (3.6 kilograms) of elemental zinc per gallon of coating, as applied; and

(b) Is used for the express purpose of corrosion protection.

(15) "Pretreatment wash primer coating" means a coating that contains a minimum of 0.5 percent acid, by weight, and is applied only to bare metal to etch the surface and enhance adhesion of subsequent coatings.

(16) "Rubber camouflage coating" means a specially formulated epoxy coating used as a camouflage topcoat for exterior submarine hulls and sonar domes.

(17) "Sealant coating" means an epoxy coating applied over thermal spray aluminum surfaces.

(18) Ship.

(a) "Ship" means a marine vessel used for military or commercial operations, including self-propelled vessels, those propelled by other craft (barges), and navigational aids (buoys and markers).

(b) "Ship" includes:

(i) All military and Coast Guard vessels;

(ii) Commercial cargo and passenger (cruise) ships;

(iii) Ferries;

(iv) Barges;

(v) Tankers;

(vi) Container ships;

(vii) Patrol and pilot boats; and

(viii) Dredges.

(c) "Ship" does not include offshore oil and gas drilling platforms unless they are moved to an on-shore marine vessel coating operation.

(19) "Special marking coating" means a coating that is used for safety or identification applications.

(20) "Specialty interior coating" means a coating used on interior surfaces aboard U.S. military vessels pursuant to a coating specification that requires that the coating have specified fire retardant properties and a toxicity index of less than 0.03, in addition to the otherwise applicable military physical and performance requirements.

(21) "Thermoplastic coating" means a vinyl, chlorinated rubber, acrylic, or bituminous resin coating that is used to recoat a vessel with the same type of coating as its existing coating.

(22) "Undersea weapons systems coating" means a coating applied to any component of a weapons system intended to be launched or fired from under the sea.

(23) "Weld-through (shop) preconstruction primer" means a coating which provides temporary corrosion protection for steel while it remains in inventory.

C. Coating Requirements.
