Polyester-Based Coatings for Corrosion Protection

Abstract

The article is the first review encompassing the study and the applications of polyester-based coatings for the corrosion protection of steel. The impact of corrosion and the challenges encountered thus far and the solutions encountered in industry are addressed. Then, the use of polyesters as a promising alternative to current methods, such as phosphating, chromating, galvanization, and inhibitors, are highlighted. The classifications of polyesters and the network structure determine the overall applications and performance of the polymer. The review provides new trends in green chemistry and smart and bio-based polyester-based coatings. Finally, the different applications of polyesters are covered; specifically, the use of polyesters in surface coatings and for other industrial uses is discussed.

The Tribological and Mechanical Properties of PI/PAI/EP Polymer Coating under Oil Lubrication, Seawater Corrosion and Dry Sliding Wear

“…Duan et al [ 22 ] prepared a Triton X-100-modified fluorinated graphene and ZIF-8 composite epoxy coating, and the tests showed that the CoF of the coating was 0.15 under dry sliding wear at a load of 5 N and a sliding speed of 10 mm/s. The polymer coating is not only self-lubricating but also corrosion resistant [ 23 , 24 , 25 ]. Ren et al [ 26 ] prepared an h-BN@PDA epoxy coating and found that the corrosion potential of the composite coating in a 3.5 wt% NaCl solution was 0.1 V. Gu et al [ 27 ] studied the effect of modified graphene oxide (BGO) on the corrosion resistance of epoxy coatings and found that the resistance of the epoxy coating with 0.1 wt% BGO was 1.03 GΩ·cm 2 in a 3.5 wt% NaCl solution.…”

Green fluorescent unsaturated polyester/graphitic carbon nitride quantum dots nanocomposites: Preparation and study of UV-resistance, mechanical and viscoelastic properties

“…13 In order to strengthen and improve the various properties of the nanocomposite coatings such as thermal stability, mechanical features, viscoelastic characteristics, UVprotection and etcetera, one could benefit from organic and inorganic nanofillers such as ZnO, Fe 2 O 3 , TiO 2 , Al 2 O 3 , clay, graphene oxide, silica nanoparticles in addition to carbon nanotubes and carbon quantum dots. [14][15][16] During the past decades, usage of polymer substances has been rapidly increased, however it has been well proven that the fast optical degradation of these substances is possible when exposed to the natural air admission. 17,18 UV radiation could create photo-oxidative degradation to the effect that it causes breaks in the polymer chains, creating of radicals and molecular weight loss that these weaken the mechanical properties and produce useless products.…”

Fabrication of nano calcium fluoride impregnated organic polyester alkyd coating for anticorrosive and antibacterial applications

“…Alkyd resins are polyesters that are commonly used in the surface coating industry for decoration and protection on any type of material such as metals, walls, and wood. [1][2][3] Alkyd coatings have high reliability and durability and provide high gloss. To develop an effective coating, the formulation should satisfy many conditions like good aesthetic appearance, increased spreading rate, anticorrosion ability, etc.…”
