MIL-DTL-81706B
4.5.6 Vertical adherence (forms IV and V only). Each panel prepared as specified in
4.4.2.2 shall be placed in a 600 ml beaker and weighed with the beaker to the nearest 0.1 gram.
The weight for each panel shall be recorded. One quart of the form IV or form V material (with
the required water added) shall be thoroughly mixed and allowed to stand for not less than 24
hours. After the 24-hour period, an amount of material shall be transferred to a 600 ml plastic
beaker (not the beaker used in the weight determinations) such that the beaker is almost filled.
Four inches (up to the pencil line) of each panel shall be immersed, one at a time, in the coating
material. The panel shall then be lifted vertically above the surface of the material and allowed
to drain for 45 seconds. The panel shall then be transferred without rinsing to the beaker in
which it was originally weighed and the coated panel with the beaker shall be reweighed to the
nearest 0.1 gram. The vertical adherence weight shall be determined for each panel by
subtracting the original weight of the panel and the beaker from the weight of the coated panel
and beaker. The results obtained for each panel shall be averaged to determine compliance to
3.8.
4.5.7 Storage stability. After having been stored in its original container for the specified
time period (see 3.9) under daily mean temperatures within 35 to 95 °F (2 to 35 °C), with peak
ambient air temperature not exceeding 115 °F (46 °C), the product shall be tested in accordance
with table I to determine compliance to 3.9.
5. PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified
in the contract or order (see 6.2). When packaging of materiel is to be performed by DoD or in-
house contractor personnel, these personnel need to contact the responsible packaging activity to
ascertain packaging requirements. Packaging requirements are maintained by the Inventory
Control Point's packaging activities within the Military Service or Defense Agency, or within the
military service's system commands. Packaging data retrieval is available from the managing
Military Department's or Defense Agency's automated packaging files, CD-ROM products, or
by contacting the responsible packaging activity.
6. NOTES
(This section contains information of a general or explanatory nature that may be helpful,
but is not mandatory.)
6.l Intended use. The conversion coatings covered by this specification are intended for
use, throughout the Department of Defense, on aluminum and aluminum alloy substrates that are
not anodized. They are used to repair anodize coatings on aluminum. They are designated as a
post treatment to ion-vapor deposition (IVD) aluminum used on many military platforms as a
cadmium alternative or galvanic corrosion inhibitor. Type I and II conversion coatings provide
corrosion protection on unpainted items, as well as improve adhesion of paint finish systems on
aluminum and aluminum alloys. Conversion coatings covered by this specification exceed
commercially available products due to the nature of their use on aircraft. All conversion
coating applications in accordance with this specification are assumed to use type I unless the
