The properties of TETILON waterborne coatings coated in three kinds of condition of coated with rust,wet and oil were studied.The results show that the thickness of the rust layer has a great influence on the performance of film when coated with rust.The performance of film is excellent if rust in surface is removed.When coated with wet,the performance of film is excellent if the substrate surface can be without obvious accumulation of water marks.It is necessary to wipe the oil on the surface with a clean cotton cloth when coated with oil.The adhesion of film can reach 1 level,but the wet adhesion decreases.
