Brite Zinc coatings meet and exceed the performance requirements of DOD-P-21035A which addresses high zinc dust content paint for regalvanizing welds in galvanized steels. This spec is approved for use by all interested Commands of the Department of the Navy and the Marine Corps and is available for use by all other Departments and Agencies of the Department of Defense.
Key performance requirements include: Toxicity: The material shall have no adverse effects on the health of personnel when used for its intended purpose.
Materials: The paint shall consist of zinc dust conforming to type I of TT-P-460, either ready-mixed or in a two-compartment container with resins, oils, and solvents properly processed to conform with all requirements as herein specified.
Manufacture: When the paint is supplied as a ready-mixed, single-package product, the component raw materials shall be mixed and ground as required to produce a product which is uniform, free from dirt and grit, entirely suitable for the purpose intended, and is full conformity with the requirements of this specification.
Condition in Container: The mixed paint shall be capable of being broken up to a smooth, uniform consistency. It shall not increase more than 15 Kreb units in viscosity or increase more than 2 hours in drying time. It shall not liver, curdle, gel, or show any other objectionable properties for at least 1 year after date of manufacture, when tested as specified.
Application Characteristics: The mixed paint, when tested as specified, shall be capable of being brushed out without excess drag on the brush. When dry, the brush-coated surface shall be free from sags, runs, wrinkles, excess brush marks, or other film defects. The film shall exhibit good adhesion and a smooth, uniform appearance.
Salt-Spray Resistance: The uncoated area of the test panel shall not be completely rusted. The coated area shall show less than 5 percent rust. There shall be no blistering, loss of adhesion, or other film failure, except pinpoint rusting and white corrosion product, when tested as specified.
Knife Test: A film of the mixed coating, when prepared and tested as specified, shall be tough and hard and shall adhere tightly to the metal panel. It shall be difficult to furrow off with the knife and shall not flake, chip, or powder. The knife cut shall show beveled edges.
Stability in Partially Full Container: When tested as specified, the vehicle shall exhibit no evidence of skinning.
Material Safety Data Sheet: The procuring activity shall be provided a material safety data sheet (MSDS) and included with each shipment of the material.
Intended Use: Regalvanizing of welds in galvanized steels
Units of Purchase: 1 U.S. gallon & 12 1/2 oz. aerosol
Packaging: Paint will be held in covered storage no more than 1 year from date of initial packaging
