efficiency improvements over other wash primer systems while
eliminating chrome as the corrosion inhibitor,” Cancilla add-
ed. “Our Desoprime CF/CA7521 chrome free structural primer
is the first such system to have passed stringent tests required
of structural coating applications. Finally, our Desothane
Solar Heat Management Coatings have been developed and
commercialized to reduce overall absorbed solar heat loads,
leading to reduced skin and interior temperatures, improving
ground cooling requirements, and expanding the color design
palette for critical composite structures. These and many more
new products have been launched and are being developed to
contribute to the overall efficiency of the aviation industry and
its products.”
Sherwin-Williams Aerospace Coatings recently introduced
CM0481030, a two-component urethane surface. Its quick
drying benefits increase shop productivity by reducing process
time for topcoat preparation. This new composite surfacer also
provides outstanding gloss holdout, resistance to film shrinkage,
easy sanding and flexibility, the company noted.
“Intended for use on composite for the aircraft exterior and
parts, the new CM0481030 surfacer is ideal to fill and cover
surface imperfections to create a smooth surface for topcoat
applications,” said Julie Voisin, product manager at Sherwin-Williams Aerospace Coatings. “When applied, this composite surfacer forms a tough film with excellent recoat/intercoat
adhesion properties and is compatible with Sherwin-Williams
topcoats including SKYscapes Polyester Urethane basecoat-clearcoat topcoat system.
Sherwin-Williams also introduced SKYscapes General
Aviation Clearcoat (CM0850CC1), an aircraft grade, polyester urethane designed to be used over SKYscapes Polyester
Urethane basecoat on exterior surfaces of general aviation aircraft (i.e. Non-Skydrol aircraft).
This high performance product is designed to deliver the
maximum in appearance and productivity in a high gloss, durable finish that can be easily cleaned, buffed and repaired.
This new general aviation clearcoat features fast dry times
that lead to improved productivity, is easy to mix and provides
excellent flow and leveling.
“This basecoat-clearcoat system offers virtually every color
under the sun, whether new or expertly custom-matched,” said
Voisin. “It’s quick, simple application means that aircraft spend
more time in-service and less time in the shop. Aircraft owners
demand on-time delivery and the SKYscapes Polyester Urethane
basecoat-clearcoat system can reduce paint-process time by as
much as 30 percent, helping meet customer demand for aircraft
turnaround. This is because this new system cures at ambient
temperature in half the time of other single-stage systems.
The new CM0850CC1 clearcoat can also be used over
Sherwin-Williams Acry Glo acrylic urethane topcoat in conventional and high solids opaque and metallic colors. Sherwin-Williams provides the finest in quality aerospace coatings and
delivers custom solutions for commercial, military and general
aviation including a full-range of specialized livery color options in a line of products for an outstanding, durable finish.
Additionally, its widespread global distribution network dramatically speeds up the custom order process so that they can
be delivered and applied within only a few days.
AkzoNobel said it is the first aerospace coatings company
to offer new basecoat/clearcoat systems approved by the top
four commercial aircraft OEMs. “We also launched two high
performing chrome free primer products: Aerodur 2118, a
true high solids primer for use on aircraft exteriors, approved
to AMS 3095 and Aerodur 2100, a unique product utilizing
magnesium as the corrosion inhibitor,” said Griffin. “This technology has proven time and again to outperform competitive
systems in both lab testing and field evaluations. The Aerodur
2100 is approved to AMS 3095 and the newly released Mil-PRF
32239 specification.”
AkzoNobel is also investing in the next generation of technologies to deliver a chrome free structural primer, very fast
drying polymers to drive more efficiencies in maintenance and
manufacturing, and reducing the number of raw materials
sourced from crude oil to deliver more sustainable long term
solutions to the market. “AkzoNobel’s long-term strategy is to
focus on innovation to develop products that do more with
less,” said Griffin. “The strategy, called Planet Possible, is a
commitment that helps us bring more value to our customers
and to society in general.” CW
