MIL-DTL-24441D(SH)
3.6.4 Stability in partially full container. When tested as specified in 4.5.12, a three-quarter filled, closed
0.25 -liter (8-ounce) glass jar of part A and part B shall show no skinning, livering, curdling, seeding, hard caking,
loss of thixotropy, or gummy sediment. After this aging, each component shall remix readily to a smooth uniform
mixture with a consistency not greater than 625 grams to produce a 200 revolutions per minute (r/min) Krebs-
Stormer shear rate (121 Krebs units (KU)).
3.6.5 Dilution stability. When thinned as specified in 4.5.13 and mixed as specified in 4.5.1, paint shall remain
stable and uniform showing no precipitation, separation, or curdling.
3.6.6 Odor. The odor shall be characteristic of the volatiles permitted.
3.6.7 Condition in container.
3.6.7.1 Components. When tested as specified in 4.5.14, each component shall be readily broken up with a
paddle to a smooth, uniform consistency and shall not liver, gel, or show any other objectionable properties for at
least 1 year after date of acceptance.
3.6.7.2 Paint. When tested as specified in 4.5.14, components which have been stored for at least 1 year in
their original containers, when mixed as specified in 4.5.1, shall produce a paint which meets all requirements of this
specification and the applicable specification sheet, except that the consistency of the mixed paint reported in grams
shall be not greater than 625 grams (121 KU).
3.6.7.3 Accelerated storage stability. When tested as specified in 4.5.14.1, components shall meet the
requirements of this specification and the applicable specification sheet for consistency, fineness of grind, and
condition in container. Mixed paints from these components shall have a consistency of not more than 625 grams
when tested in accordance with ASTM D562, and, when tested as specified in table III, shall meet the requirements
of the applicable specification sheet for dust-free time, dry-hard time, fineness of grind, pot life, sag, gloss,
sprayability, and condition in container.
3.6.8 Immersion tests. When tested as specified in 4.5.15, qualification paint test panels shall perform at least
as well as the reference panels for blistering resistance and the average adhesion, both to the substrate and the
original paint in the recoated area, shall be not less than 95 percent of average adhesion values measured for the
reference panels in the same areas.
3.6.9 Solvent resistance. When prepared and tested as specified in 4.5.11, paint films shall show no wrinkling,
softening, tackiness, swelling, blistering, loss of adhesion, or other sign of solvent attack when examined.
3.6.10 Cathodic protection (formula 159 only). When formula 159 is tested as specified in 4.5.19, the coating
shall prevent corrosion in the bare metal area for not less than 48 hours. No corrosion of bare circle or any other
surface shall occur.
3.6.11 Batch specific VOC certification. Manufacturers shall prepare label instructions in accordance with
29 CFR 1910. Each container shall be affixed with a hazardous chemical warning label in accordance with 29 CFR
1910.1200. To comply with the Environmental Protection Agency (EPA) National Emission Standards for
Hazardous Air Pollutants (NESHAP) requirements for shipbuilding and ship repair, the two following statements
shall appear on each paint can label:
a.
Certification that the paint in the container meets the NESHAP requirements for shipbuilding and ship
repair.
b. Statement of the ratio of volatile content to solids expressed as grams of volatile organic hazardous
pollutants (VOHAPS) per liter of solids.
4. VERIFICATION
