Foreign countries from the late sixties on the use of aliphatic polyurethane enamel as the outer surface of the aircraft skin protective coating, which is currently a better aircraft skin enamel varieties.

Due to the comprehensive performance of aliphatic polyurethane enamels, it is estimated that the scope of application will be gradually expanded in the future. Polyurethane enamel construction than the general nitro paint, alkyd paint more difficult, I participated in the polyurethane enamel test jet on the plane, has accumulated little experience, and now write down to discuss with everyone. 1. Painted polyurethane paint around the screws and removable lid edge paint off the problem
