“…In vehicle fabrication, ERs are commonly used as anti-corrosive coatings as a primer to metal parts. These coatings decrease the risk of corrosion and rust formation on the metallic components of the vehicles decreasing maintenance costs [235,236]. They are also applied in protective paints, as adhesives and sealants and also in the preparation of high-performance composite materials that are broadly used in the aircraft industry due to their optimal mechanical properties, light weight and fire-retardant properties [237,238].…”

The urgent need to replace fossil resource-based products is considerably increasing in the past few years, resulting in the search for more sustainable materials, with the aim of reducing the wastes from polymer pollution, solving economic and environmental issues. This is even more relevant in industrial fields, where toxic compounds are the basis of their polymeric formulations. Herein is reported the most relevant advances of epoxy resins (ERs) in the past decade, with great emphasis on the replacement of bisphenol A (BPA), leading to the production of renewable-based ERs with good properties. The synthesis of ERs based on renewable sources, such as vegetable oils, phenolic compounds, sugars and the outcome in the material's structure is explored within this review. Emphasis is also given to the use of new biobased curing agents and biofillers to enhance the biocharacter of the ERs.

“…Specifically, mild steel is extremely corrosive in marine environments, resulting in the deterioration of its strength, security, and appearance. Surface coating is the most effective corrosion protection method in which the corrosive medium could be isolated. − Currently, paints have been commonly applied on steel to provide a dense barrier against the corrosive environment to protect steel surfaces from aggressive substances owing to their convenient manipulation and cost-effective application. , However, the anticorrosive coatings mentioned above are difficult to fabricate on a wet surface of mild steel or in aqueous conditions. Widely used paints have poor underwater durability and low tensile strain and are prone to cracking, which leads to the failure of the anti-corrosion effect.…”

Hydrogels are formed through the cross-linking of hydrophilic polymer chains within an aqueous microenvironment. A novel synthesis strategy, UV-initiated frontal polymerization to quickly synthesize bubble-free, selfpropagating hydrogel anticorrosive coatings in aqueous conditions, was presented, in which the self-propagating polymerization rate reached 16.7 mm min −1 . SEM, AFM, FTIR, EIS, IC, XPS, and ultra-depth-of-field microscopy were used to characterize the surface morphology and anti-corrosion properties of the hydrogel coating. The addition of nano-SiO 2 formed dense hydrogen bonds, and the stability of the three-dimensional network was enhanced. Underwater, the hydrogel coating could physically block corrosive media from reaching steel surfaces, and it was 75% effective at blocking chloride ions after 7 days under osmotic pressure. In addition, 1,2,4-triazole accumulated on the steel surface, and then the active anti-corrosion function took effect. This paper provides the basis for the in situ synthesis of hydrogel anticorrosive coatings on the surface of mild steel in a wet or underwater state.

“…The effective protection will be provided if the coating is sufficiently impermeable and evenly stretched without any break. Depending on the final application of the coated element, the coating thickness can amount to several hundreds of micrometers [8][9].…”

Increasingly, many conventional and advanced automotive coatings applications demand materials with well-defined surface properties, fulfilling specific requirements and affecting automotive industrial development. The main assumption for the study was to analyze the microstructure and adhesion of epoxy powder coating on a steel substrate. The results of optical microscope metallographic, SEM/EDX, XRD analysis and adhesion test are presented.
