be of synthetic origin and not naturally occurring. The titanium dioxide shall be a rutile, chalk
resistant type conforming to ASTM D476, type III or IV. If other tinting pigments are used to
match the spectral characteristics, these additional pigments shall have good color stability.
When tested in accordance with 4.6, no component of the coating shall contain lead, cadmium,
cadmium compounds, and hexavalent chromium. Compounds of antimony, arsenic, beryllium,
cyanide, manganese, mercury, nickel and selenium shall be absent. The flattening pigment
materials shall be of polymeric based polyurethane or urea formaldehyde condensation type
polymers or other polymeric composition. The amount shall not exceed the limits of table VIII.
Glass beads for Interior Aircraft Black, 37031 shall conform to TT-B-1325, type I, grade B and
shall conform to the amount specified in table VIII.
3.4.1.1 Lead content. The lead content shall not exceed 0.05 percent by weight of total
nonvolatile content upon analysis as specified in 4.6.6.
3.4.2 Nonvolatile vehicle. The nonvolatile vehicle shall be a hydroxyl terminated prepolymer
reacted with an aliphatic polyisocyanate. The IR spectrum of the partially cured resin shall show
the presence of aliphatic polyisocyanates and shall contain no aromatic polyisocyanates when
determined as stated in 4.6.7.
3.4.3 VOC content. The VOC content for the types of coatings shall be as specified in 1.2.1 and
tested in accordance with 4.6.8.
3.4.4 VOHAP content. All types of coatings, except for type VIII aerosols, shall be VOHAP-
free when tested in accordance with 4.6.8.1.
