Abstract：Modern aircraft skins adopt more composite molding parts，because thecomposites haveno electricconductivity，deviser pavingthebrasswires orpaintingconductivelacqueronthecompositesurface to made itconductive.P99 conductive lacquer （DAG1415M）bywayofa silverdispersed ina thermoplasticresin，resistance smalnesand beterelectric conductivityonthecompositesurface.Buttheresistancevalueof theconductivelacquerisinstabilityandlowadhesion in the manufacturing，giving an efecton theresult ofthe aiframe lowresistance scale.The painting meansof theconductive lacquer was research to settle the problem in the manufacture in the paper.

Keywords：composite surface; conductive lacquer ; silver dispersed thermoplastic resin; low resistance measurement
