In order to solve the indentation problem of aluminum hub in manufacture and transportation processes,a comparison between the anti-indentation transparent paint NP-17 and the ordinary transparent paint KF20-0010/1 has been made to verify the feasibility of the application of the anti-indentation transparent paint NP-17 in aluminum hub.Firstly the anti-indentation property of the sprayed huh and the film properties(adhesion,hardness,chipping resistance,CASS,salt spray test,filiform corrosion,water resistance,moisture resistance,cleaning agents resistance)are investigated.Secondly the anti-indentation mechanism of transparent layer is analyzed.Finally the application of the anti-indentation transparent paint NP-17 in aluminum hub is evaluated.The result suggested that the transparent paint NP-17 with better anti-indentation performance than the ordinaiy transparent paint RF20-0010/1 and qualified film properties could be applied.
