Flexible Wing Coatings

AkzoNobel’s new generation of super-flexible wing coating minimizes application and drying times, cuts wing coating weight by more than half and VOC emissions by 90% compared to conventional wing coatings.

Aeroflex HS 113F01 is an ‘in-spar’ coating, used on the upper surface of the fixed part of a wing. During flight, this part of the aircraft is subject to considerable movement, which means a coating must stretch with it to avoid cracking. The more flexible a coating is, the better.

New Resin System

The proprietary resin system in the new coating has been designed to exceed the most stringent industry needs. Not only is it exceptionally flexible, it has enhanced, chemical and scratch resistant properties and increased color stability. There are also important cost and environmental benefits – particularly as the minimal surface roughness of the new coating contributes to greater fuel efficiency during flight.

Saves Time and Money

Only one comparitively thin layer – 30 to 40 microns – of the Aeroflex HS 113F01 is needed to achieve the necessary coverage and this has a ‘dry to step’ time of just three hours, considerably reducing labour costs. The extremely low density of the paint film, combined with low layer thickness, can reduce the total weight of a wing coating system by up to 57%.

Your Environmentally Friendly Option

A high solids polyurethane paint, Aeroflex HA 113F01 gives off less than 420 grams of harmful VOCs (volatile organic compounds) per litre, complying with the Solvent Emissions Directive (SED). Taking into account with the specified layer thickness, this means the amount of solvents emitted into the environment is an extraordinary 90% less than with a conventional wing coating system.
