Preparation and Performance Analysis of Fluorocarbon Resin Varnish on Aircraft Skin
One kind of fluorocarbon skin varnish was developed and subjected to a series of performance tests.The skin varnish is used with primer and base paint to have good mechanical properties,low temperature impact resistance and medium resistance.At the same time,it shows good anti-aging performance in the ultraviolet aging test.After 1 500 hours of ultraviolet aging,it still has 90%gloss retention,and the color difference changes ΔE*ab＜3.
