Aerospace Developing Solar-Reflective Coatings for Aircraft Windows
June 12, 2009
PPG Industries' aerospace transparencies business is developing
coating technology for aircraft cockpit and passenger-cabin windows
that reduces solar heat transmittance. The new coatings will be
on display at the Paris Air Show June 15-21 at Le Bourget Exhibition
Center in Paris.
The coatings have a neutral appearance for glass and plastic windows.
"Unlike other aerospace solar-reflective window coatings,
PPG Aerospace coatings will not be visibly reflective but will be
color neutral for the attractive aesthetics important to our customers,"
says Anthony Stone, PPG Aerospace global director, new business
development for transparencies.
"Our tests have shown solar transmittance for a stretched-acrylic
cabin window with a solar-reflective coating to be about half that
of an uncoated window while maintaining high visible light transmittance,"
Stone adds. "Passengers and crew will experience a noticeable
improvement in comfort, especially when the air conditioning is
not operating while an aircraft is on the ground."
PPG expects to qualify its stretched-acrylic cabin window coatings
this year with a major airframe manufacturer and to apply the technology
to glass cockpit windows, according to Stone.
