FIGURE 62-21 MAIN ROTOR BLADE PAINT SCHEME
62-52 Painting
CAUTION
If force-drying paint, do not exceed 175°F surface temperature
on blade; monitor blade temperature by temporarily installing
P/N 110-2 Telatemp on blade skin.
1. Mask area to prevent overspray contamination.
2. Clean bare metal to be painted with a lint-free cloth dampened with enamel cleaner (see
Approved Materials, Section 20-70).
3. Prime bare metal with at least two coats of epoxy primer. Scuff first coat of primer
with 320 grit abrasive paper (or very fine Scotch-Brite), and wipe down with a lint-free
cloth dampened with enamel cleaner prior to applying new coat.
NOTE
Best results are achieved if primer is allowed to air-dry for 12
hours prior to top coat application.
4. Refer to Figure 62-21. Apply dark gray, flat black, white, and/or yellow Dupont Imron
polyurethane enamel (or equivalent; see Approved Materials, Section 20-70), as required,
to primed area in accordance with paint manufacturer's recommendations.
NOTE
Allow Imron paint to cure at least 72 hours before flying in
erosive conditions (such as drizzle, rain, or dust).
5. Remove masking materials.
