Adhesion and anticorrosive properties of DTM coating as related to primer coating

Abstract

High worldwide prevalence of steel in the construction of buildings and infrastructure is associated with high costs that are due to the sensitivity of steel to corrosion. To reduce the steel structure corrosion protection costs, great efforts are currently made to develop new technologies that would reduce working time and extend service life of corrosion protection systems. Due to an increasing use of the “direct to metal” (DTM) system for corrosion protection of steel structures, this system was tested in the scope of this study and compared with the systems involving the use of primer coating. The tests were carried out on three types of corrosion protection systems.
