Compared with conventional multi-coating system

self-stratification coating

capable of producing multilayer structure in one operation

results in outstanding interfacial adhesion

low production cost and long service life .In this article

the self-stratifying processes and corresponding driving forces have been reviewed and suggested

and the various factors effecting on self-stratification have been discussed in detail .The progress in self-stratification coating based on solventborne

waterborne and solventless coatings has been expatiated .The coating has widely been applied in many fields

and its investigation should focus on environmentally friendly coating for the future .
