The anticorrosive properties of sol-gel films doped with hydrotalcite nanoparticles applied on tinplate

Electrochemical and Mechanical Behavior of Uv Curing Paint on Hybrid Films Modified With Polyethyleneglycol Plasticizer Applied on Tinplate

“…The tinplate usually has a full or partial tin oxide coating (SnOX), which may contain stannous oxide (SnO) or stannic oxide (SnO), including its hydrated forms. The presence of excessive amounts of these oxides can alter the appearance, weldability of the foil and the ability to receive organic coatings [1,3].…”

“…The Tinplate is a laminated sheet of carbon steel, coated on both sides with tin by the electrodeposition process, producing a thin layer of FeSn 2 , a layer of tin and tin oxide, because of the fusion process of Sn, after the electrodeposition [1][2][3]. The thickness of the metal sheets significantly influences the mechanical properties of the material.…”

“…These coatings are applied internally and externally in a metallic container, 1 and their function is to insulate the surface of the container so that there is no interaction between the packaged product and the environment [5]. The UV curing process is an environmentally friendly process is what stands out as the main advantage of this technology [5].…”

“…Currently, tinplate, which is used in the packaging sector is formed from a metal substrate comprised of a steel base that has undergone a surface treatment, to produce a fine FeSn 2 layer, a tin layer, and a layer of tin oxide [1,2].…”

Corrosion Mechanism Suggested Based on Electrochemical Analysis and SVET for Uncoated Tinplate and Post Coated With a Hybrid Film

“…Along the years, researchers have been working on modifying the thickness of these materials, aiming, among other things, to reduce costs. Steel represents up to 80% of the cost of packaging and any reduction in thickness of the plate is economics 5,6 . Regarding the quality of tinplate, it is worth mentioning the presence of tin oxide on the surface and the passivation layer.…”
