Coating A layer of material applied to a surface to form a protective, decorative/cosmetic, or functional solid film after drying (or liquid film in some cases).

Coating System One or more coats of one or more specified coatings.

CoatingSysName This is the “coating system name” used to identify/designate a particular coating system in an SOW or PAINT SCHEDULE DWG.

The CoatingSysName is defined in Section 2 AUTHORIZED COATING SYSTEMS, and maps to one or more CoatingSpecName(s). The CoatingSysName describes the number of coats required to complete the system and which CoatingSpecName(s) are authorized for use.

https://www.navsea.navy.mil/Portals/103/Documents/SSRAC/NSI/FY24/009-32_FY24_pkg.pdf v1.0 Page 3 of 44

CoatingSpecName This is the “coating specification name” used to identify/designate a particular coating specification herein.

Each CoatingSpecName is defined in Section 3. COATINGS SPECIFICATIONS AND PRE-APPROVED PRODUCTS. A CoatingSpecName will map a coating specification to one or more pre-approved coating brand names that meet the specification that maps to the CoatingSpecName.

FRP, FRE These are Fiber Reinforced Plastic, Fiber Reinforced Epoxy, and Fiber Reinforced Polyester;

“fiberglass” hulls/components/surfaces.

SEA CHEST A recess in the hull used to couple cooling water suction lines to sea water via flanges and pipe weldments.

MIST COAT A mist coat is 1.0-2.0 mils (wet film thickness) of paint applied to promote adhesion or compatibility between unlike materials for spray applications only. Its a low viscosity, thin film, epoxy coating generally applied to an inorganic or organic zinc primer that penetrates the porous zinc primer and allows the occluded air to escape through the paint film prior to curing.

PRESERVATION

PLAN

STRIPE COAT A hand-brushed, rolled, or sprayed coat of paint that is specified for a coating system, that ensures the specified coating thickness encompasses all edges, as well as at least one-inch border outside each edge, and is neat in appearance. Minimize excess thickness, as well as streaks and drops of paint. The STRIPE COAT color must contrast with the primer coat (or other coat) beneath.

All corners/edges, weld joints, etc. of a surface must be STRIPE COATed.

For multi-coat systems with inorganic zinc as the primer coat, apply the STRIPE COAT following the mist coat application, using the same coating used for the mist coat applied to the top of the zinc primer coat.

At a minimum, and in general, a STRIPE COAT must be applied after the primer coat (or the first appropriate coat), but subsequent STRIPE COATs may be applied to achieve proper, uniform coating thickness across all surfaces.

TIE COAT Similar to a MIST/TACKY COAT, except the specific tie coating material is formulated by manufacturers soley for the use in a particular coating system design. Often used in underwater hull coatings between the last AC coat and the first AF coat, or to otherwise address a chemical or other incompatibility between two coats. Sometimes called a “TACK COAT”.

NOTES: Refer to “Application Guidelines, Underwater Hull Foul Release”, available from International, when preparing a PRESERVATION PLAN for this system.

Foul-Release Coating System SPECIFICATION - A nontoxic coating for boat hulls that resists attachment of fouling. The coating has a low-energy surface, and its primary mechanism for releasing fouling does not rely on dissolving, polishing, eroding, or reducing in thickness. An equivalent coating to the products specifiedherein must meet the following criteria:

1. The coating, applied and cured as directed by the manufacturer, must be allowed to foul for 30 days in subtropical waters. When exposed to flowing seawater at 18 knots for 30 minutes, the coating must release at least 80% of the settled fouling.

The area covered by residual fouling must be measured and recorded. This cycle https://qpldocs.dla.mil/search/parts.aspx?qpl=1720&param=QPL-24647&type=256 https://qpldocs.dla.mil/search/parts.aspx?qpl=1720&param=QPL-24647&type=256 https://qpldocs.dla.mil/search/parts.aspx?qpl=1720&param=QPL-24647&type=256 v1.0 Page 21 of 44 must be repeated six times. At the conclusion of each cleaning, the area covered by residual fouling must not be greater than at aFny previous cleaning.

2. Have received EPA concurrence that registration is not required.

3. Easily cleaned by low pressure washing (<1000 psi) or by light wiping with sponges or soft cloth.

INORGANIC ZINC SPECIFICATION - A self-curing, solvent-based inorganic zinc-rich primer for use on properly prepared steel surfaces. This high-solids, VOC-compliant, inorganic zinc-rich primer protects steel galvanically and halts sub-film corrosion. When damaged, it continues to protect the underlying steel by cathodic protection. It will withstand severe weather conditions and aggressive exposures. This primer may be top-coated or used without topcoat, for instance, on buoy decks. An equivalent coating to the products specified herein must meet the following criteria:

1. Although optimal relative humidity may be higher, the coating must be able to cure at a relative humidity down to 50%.

2. Other salient characteristics:

a) Color: Gray (Green-Gray is acceptable)

b) Metallic zinc content: 80% minimum by weight in dry film

c) Adhesion (ASTM D4541): 1000 psi min

d) Flexibility: No cracks when bent 180º over a 1-inch mandrel

e) Impact resistance (ASTM D2794): 60 inch-pounds min.
