Abstract：The adhesion between diferent sealants and diferent coating systems was studied，and the changes in adhesive properties of thepainted surface without sanding and after sanding were verified.The results showed that HM120 B-4 sealant had poor adhesion to a variety of coating systems，and it was necessary to full polish HM120 sealantbefore applying HM12O sealant on the topcoat. HM113 and HM1123 sealants had poo adhesion to QH-15 QFS -15B，BFJ-1901-1 BFJ-1901-2 and CTN-3728 CTA -3761 coating systems，but had good adhesion to QH -15 QFS -15E3 and HDY -HO6 -Y010 HDY -S04 -22 coating systems，and could be coated without grinding.HM317 sealant had good adhesion adaptability to QH -15 QFS-15B coating system，and could be coated without grinding.It was not recommended to apply JLG -1O3 B -2 sealant to the surface of the topcoat.
