In the aeronautics industry, galvanic treatments and painting are the final processes of a working cycle, yet they are essential not only for aesthetics reasons, but also to prevent materials from corroding.

In fact, aircraft surfaces are subject to adverse environments, both natural and artificial, and the lack of protection against corrosion could result in decreased efficacy and duration of structural components.

To protect metals from corrosion, the following procedures need to be performed as part of the working cycle: Wash primer, Primer and Topcoat.

PRIMER: CHROME FREE EPOXY PRIMER, according to the specifications:
   MIL-P-53022
   MIL-PRF-85582
LOW REFLECTIVE CHROME FREE EPOXY PRIMER, according to the specification:

Liquid Penetrant Inspection

Liquid Penetrant Inspection is a control process that is able to detect discontinuities opened to the surface. it is applicable to every kind of non porous material, both magnetic and amagnetic (Steels, Aluminum Alloys, Ceramics, Plastic Materials, Glass, bronze, etc) and is base on the capillarity properties of some liquids. The Penetrant Liquids can be both red coloured or Fluorescent (visible only under Black UV Lights inside darkened booths) and they are Always used together with another product with coloured called developer.
