Improvement of Wet Adhesion of Organic Coatings by Thin Adhesion Layer

Abstract

An attempt was made to discuss several mechanisms of wet adhesion to improve the performance properties of organic coatings against corrosive and destructive environment. The effect of cooperative bonding to improve immobilization during film formation by crosslinking between binder and substrate molecules was presented. It was demonstrated that the wet adhesion increased by increasing glass transition temperature (T) of the polymer. A proper confirmation of binder molecules in very thin adhesion layers increases the bonding efficiency resulting the improvement of wet adhesion of the organic coatings on the substrates. The combination of crosslinkable macromolecules used as a binder with barrier properties of the thin adhesion layer of coating can provide an interesting alternative for the common electrochemical protection for heavy duty applications.
