Abstract
This study focuses on the possibility of using siloxane resins with epoxy modification to delay corrosion of metal substrates for hydraulic applications. Formulations aimed at metal protection were designed, without including anticorrosive additives, and deposited on 11SMnPb37 steel. Thin monolayer films were obtained by dip coating in different process conditions, avoiding primers. The developed procedure was simple and able to provide solid and well-anchored coatings. They were characterized in terms of morphology, scratch and wear endurance, and?resistance to a corrosive environment. The optimum formulation and deposition parameters were found. The selected coating showed remarkable adhesion to the substrate, good mechanical properties, and resistance in a saline environment, proving to be suitable as a protective barrier against corrosion. The protective effect was ensured not by additives but through the excellent adhesion of the coating and?its endurance to scratch and wear.
