to the body of an aircraft and spoils the
overall appearance of an aircraft’s livery.
This condition commonly occurs on forward sections of commercial aircraft.
“Our 10P20-44M primer has been optimized and offers an unprecedented combination of adhesion, fluid resistance, and
topcoat compatibility for premium inflight performance,” Griffin said. “The
product is also designed to work with conventional pretreatments commonly used
in the aircraft industry, such as MIL-C-
5541 chemical conversion coatings.”
The new product has application and
environmental benefits also. It achieves
a smooth satin finish in three hours, and
does not require sanding, reducing
process time. The pot life also minimizes
waste allowing an applicator plenty of
time to utilize the complete contents. In
addition, under U.S. legislation, the
product is low VOC. The combination of
low VOC and high solids technology
means it gives off less harmful VOC and
HAPs emissions than conventional and
waterborne primers.
ANAC’s 10P20-44M primer is currently in use in the maintenance sector, and will now be available for new
Boeing aircraft.
In addition, a new generation of structural coatings that combines toughness
and flexibility with improvements in
handling, application and environmental
properties has been launched by ANAC
and approved to Airbus and EADS
Eurofighter specifications.
The new Aerowave series of products
is designed for use primarily on internal
structures, some of which may be sealed-in and not exposed for more than 30
years. The product range includes a chromated primer for metallic substrates, a
chrome-free primer for non-metallic substrates (composites), and a topcoat, pore
filler and stopper.
Sherwin-Williams Aerospace Coatings
earlier this year launched a complete
coating system—including pretreat-ment, corrosion protective primer and
topcoat—certified with SAE International’s Aerospace Material
Specification 3095 (AMS 3095) for
Airline Exterior Systems.
The new certification approves two of
Sherwin-Williams’ painting systems:
Sherwin-Williams Aerospace Coatings
CMO483928 with traditional High
Solids Chromated Epoxy Primer, and
CMO481968 High Solids Chrome Free
Epoxy Primer/Surfacer. Both systems
are finished with Jet Glo Express
Polyurethane topcoat for global after-market use as complete painting systems for commercial airline fleets.
“This certification expands Sherwin-Williams Aerospace Coatings’ presence
worldwide in the commercial market,”
said J. Marc Taylor, Sherwin-Williams
Aerospace Coatings Director of Sales.
More than 2,500 SAE Aerospace
Material Specifications (AMS) are recognized throughout the aerospace community and other industries, including the
U.S. Department of Defense, which has
adopted more than 900 of these documents into its standards. These AMS
specifications are procurement standards rather than design specifications.
AMS 3095 covers high-gloss paints for
use on civil aircraft.
According to Taylor, a quality paint
job not only protects the plane, it also
boosts an airline’s brand image. “An
attractive, well-kept fleet is an airline’s
best advertisement,” he said. “
High-quality coatings last longer, stay more
vivid and offer easy maintenance and
repair in comparison to lesser-quality
products.” CW
PPG AEROSPACE ADVANCED-PERFORMANCE
COATINGS IMPROVE DURABILITY OF F- 16 JETS
F- 16 jets flown by the U.S. Air Force Thunderbirds are
being painted with a smooth, fast-drying primer and
high-gloss, lightweight, advanced-performance coating
(APC) topcoat by PPG Industries’ aerospace business.
Desoprime HS CA7233 epoxy primer and Desothane
The high gloss colorful finish on F- 16 jets flown by the U.S.
Air Force Thunderbirds air demonstration squadron is
achieved with an advanced-performance primer and topcoat
by PPG’s aerospace coatings business.
HS CA9800 polyurethane APC topcoat by PPG Aerospace-PRC-DeSoto will improve durability of the red, white and
blue colors of the jets flown by the air demonstration
squadron, according to Duane Utter, PPG global segment
manager, military coatings and classified products.
Utter said the smooth application properties of
Desoprime HS CA7233 primer leave the surface ready for
the topcoat without sanding or other preparatory work. “The
combination of Desoprime HS CA7233 primer and
Desothane HS CA9800 APC topcoat gives a long-lasting,
high-quality gloss finish with exceptional image definition,”
he said. “This Desothane APC topcoat has superior weathering resistance and cleanability that retain gloss and color
far longer than previous coatings systems, extending the
time before repainting is needed.”
Both products offer application benefits, Utter said.
“The Desoprime primer dries faster than traditional
high-solids primers to enable faster repainting, while
the Desothane APC topcoat can be tailored at the factory to dry in as few as two hours or as many as 15 hours
to meet application requirements.”
Compared with an earlier version of gloss topcoat,
Desothane HS CA9800 APC topcoat achieves up to a five
percent weight savings because of its lower density.
