(2) Materials
(a) Use primers per DOD-P-15328, such as:
Sherwin-Williams
Thickness
(3) Application
(a) Solvent wipe. Refer to Manual Cleaning.
(b) Abrasive clean. Refer to Manual Deoxidizing.
(c) Sand to feather the existing coatings or remove existing coatings.
(d) Blow the area to remove dust; tack rag and solvent wipe.
(e) Mask surfaces that are not to receive pretreatment primer. This includes painted surfaces, sanded painted
surfaces, rubber, transparencies, cable chains, bearings, etc.
(f) Spray exposed steel surfaces with pretreatment primer DOD-P-15328.
(g) Allow the pretreatment primer to flash. Pretreatment treated surfaces must be ready to apply primer within 30
minutes. Pretreated surfaces must be recoated within four hours after application using corrosion resistant
primer meeting requirements of MIL-PRF-23377G or later.
(h) Apply the necessary coating after 30 minutes (minimum).

(2) Process
(a) Clean with a solvent wipe. Refer to Manual Cleaning.
(b) Deoxidize using ScotchBrite, or equivalent, wet with water. Refer to Manual Deoxidizing. Abrade the area to be
chemical filmed until it is uniformly bright and "white" in color. Keeping the surface wet with water, continue to the
next step.
(c) While the detail is still wet from deoxidizing, apply chemical film coating solution by brush or swab. Keep a
continuous wet film by repeated application separated by one minute time intervals. This must be done until a
detectable yellow to brown color film is formed. Typical time for application is 1 to 5 minutes at room
temperature.
(d) Blot away the excess color film treatment, using a water dampened, clean, soft cloth or swab. Use care when
blotting as the fresh film is soft when just formed. Dispose of cloths according to environmental regulations.
(e) Thoroughly flush area with water. Air dry or blow dry with oil free compressed air. Temperature must not exceed
130°F (55°C).

When using Alodine 1203, deoxidizing with ScotchBrite is only necessary if there is
heavy oxidation. To chemical film, solvent wipe, dry, and brush on Alodine 1203. After
conversion treatment, rinse thoroughly with cold water and dry.
