                TG No. 144                                                            August 1987

                    d   Application. Lusterless lacquer (NIL-L-11195) and semigloss,
                celluiose-nitrate lacquer (MIL-L-52043) may be used as a finish for automotive
                equipment and general use on ferrous metals and aluminum. Magnesium alloy
                metals are coated with-semigloss vinyl.-resin lacquer (MIL-L-14486).
                Composition of these materials is In paragraphs C-21 through C-23. These
                materials may be applied as issued if hot spray techniques are used. However,
                If the lacquers are sprayed at room temperature and below, they must be
                properly thinned. Lusterless lacquer is thinned with one part thinner to two
                parts by volume of packaged material. Semigloss, cellulose-nltrate lacquer Is
                thinned using a ratio of three parts by volume of thinner to five parts by
                volume of lacquer.

                B-3. CARC

                    a. Coatino. The CARC system consists of three different types of
                coatings; an epoxy polyamide primer used as an undercoat, an aliphatic PUP
                which is used on external surfaces, and an epoxy polyamide enamel (EPE) which
                is used on internal applications. The aliphatic polyurethane topcoat is
                available as a two component system (MIL-C-46768) and a single component
                system (MIL-L-53039). The composition of these coatings is presented in
                paragraphs C-14 and C-15. All interior surfaces are coated with a two
                component EPE (MIL-C-22750). See paragraph C-16.

                    b. Thinners.

                        (1) 1.1,1-trichloroethane Is used to thin PUP (MIL-C-46168) Type 111,
                in areas having stringent VOC air pollution limits.

                        (2) Thinner (MIL-T-81772), Type I is used to thin polyurethane
           coatings. See paragraph C-27.

                        (3) Thinner (MIL-T-81772), Type II is used to thin epoxy polyamide
                coatings and primers.

                    c. Primers. Specific primers must be used with both the exterior PUP and
                Interior poxy topcoats. information regarding these primers is in Appendix
                C. paragraphs C-1 through C-13.

                    d. Application.

                        (1) The aliphatic PUP can be applied over well-cured alkyd enamel.
                However the alkyd coating must be sound and free of absorbed or deposited
                oils, greases, waxes, etc. The aliphatic PUP cannot be applied over lacquer
                or vinyl paints due to Incompatibility.

                        (2) Recoating may be performed while the original coat is tacky. If
                the original coat has cured for 14 days or more. light scuff sanding may be
                necessary for adherence.
