Enamel, Rust-Inhibiting, Olive-Drab (TT-E-485)

TM 43-0139 c. Application. Thoroughly mix each of the components separately. Mix four parts of Component A with one part of Component B by volume and stir until well blended. An induction of 30 minutes is necessary after mixing. Epoxy primers have a pot life of 15 hours. d. Drying Time. The sprayed primer will be set to touch within five minutes and dry hard within 90 minutes. e. Thinner. Thin with MIL-T-81772, Type II. This primer may be thinned up to 20 percent by volume. 2-12. Primer Coating, Epoxy Water Reducible, Lead and Chromate Free (MIL-P-53030) a. Characteristics. This primer is a water reducible, air-drying, corrosion inhibiting, two-part epoxy system. It is lead and chromate free. b. Use. It is intended for use on pretreated ferrous and non-ferrous substrates, and is compatible with polyurethane topcoats. It contains no more than 2.81 pounds per gallon (340 grams per liter) of volatile organic componds (VOC) as applied. It is a primer for use with CARC paints. c. Application. Thoroughly stir Component A by hand until uniform. Mix Component B with Component A in the volume specified by the manufacturer. An induction of 30 minutes is necessary after mixing. Epoxy primers have a pot life of 15 hours. d. Drying Time. The sprayed primer will be set to touch within 45 minutes and dry hard within two hours. e. Thinner. Reduce the admixed primer with water. When spraying, this primer should have a viscosity of 20 seconds in a viscosimeter cup. 2-13. Enamel, Rust-Inhibiting, Olive-Drab (TT-E-485) a. Characteristics. This is a combination air-drying and baking enamel that provides a smooth, semigloss, olive-drab film, possessing excellent corrosion-inhibiting properties. b. Use. (1) As a one-coat painting system over phosphate-treated or solvent cleaned steel surfaces, such as sheet metal, metal ammunication containers, and gasoline drums. (2) For a two-coat system consisting of a primer and top coat alkyd finish, for general use. (3) As a baked primer (in a two-coat semigloss baked finish) on steel and wood. (4) As an undercoat for all metals except aluminum and magnesium. c. Application. (1) Brushing. Apply as issued or thin with not more than five percent by volume of thinner. (2) Spraying. Apply after thinning with not more than 15 percent by volume of thinner. (3) Roller. Thin to the consistency recommended by the manufacturer. d. Thickness of Coating. This depends on the purpose of the application. When used as a priming coat, a thin (0.4- 0.6 mils thickness), uniformerly applied coat is effective. When used as an intermediate or top coat, a fairly heavy coating should be applied (0.9-1.1 mils). Change 1 2-4
