East Hartford-based United Technologies Research Center (UTRC) and UTC Aerospace Systems are developing a more environmentally friendly primer to coat and protect aircraft landing gear from corrosion.
The patented pigment and primer is free of chromate, which oxidizes and can promote rust. It would be used on steel parts for commercial airplanes, said Steve Tongue, senior director, UTC Aerospace systems program office at the UTRC.
The development was announced at the Paris Air Show. UTC Aerospace is a division of Farmington-based United Technologies Corp.
Following a 16-month inspection, a field evaluation of Porter Airlines' landing gear that use the primer show no signs of coating deterioration or corrosion. UTC Aerospace is monitoring the primer's performance as it evaluates moving toward commercialization.
The primer also is compliant with European Union regulations, the company said.
"We still have a long way to go, but are encouraged by the recent advances we've made," said Tongue.
