The adhesion of epoxy cataphoretic coating on phosphatized hot-dip galvanized steel

Bajat Jelena B., Mišković-Stanković Vesna B., Popić Jovan R., Dražić Dragutin M.

The influence of hot-dip galvanized steel surface pretreatment on the adhesion of epoxy cataphoretic coating was investigated. Phosphate coatings were deposited on hot-dip galvanized steel and the influence of fluoride ions in the phosphating plating bath, as well as the deposition temperature of the plating bath, were investigated. The dry and wet adhesion of epoxy coating were measured by a standard pull-off method. The surface roughness of phosphatized galvanized steel was determined, as well as the wettability of the metal surface by emulsion of the epoxy resin in water. The adhesion of epoxy coatings on phosphatized hot-dip galvanized steel was investigated in 3wt.%NaCI.

Keywords: adhesion, phosphate coatings, hot-dip galvanized steel, epoxy coatings, corrosion
