            C-10.   MILITARY SPECIFICATION MIL-P-11414, 10 MAY 1971, PRIMER COATING,
            LACQUER, RUST-INHIBITING.

                a. This primer is a quick drying rust-inhibiting cellulose nitrate        primer
            intended for use on solvent cleaned or phosphated shells, bombs, grenades,
            tanks, trucks, ammunition, and automotive components. While developed
            primarily for ferrous metal. it has given excellent performance over
            vapor-cleaned or chemically-treated aluminum. The color of the primer         is
            characteristic of the Iron oxide or chromate pigments used. This primer
            contains Insoluble chromium VI compounds and the pigment composition Is
            limited to that listed in table C-20.


            Table C-20
            Pigment composition
                                                                         Percent by weight

                      zinc chromate (CrO3 x 2.4) and acid insoluble
                      siliceous material


                b. Depending on the solvent content, this primer is classified as
            Composition G for general use or Composition L where air pollution limitations
            are imposed. Volatile portion of the primer is controlled by that presented
            In table C-21.
