background: the advantages of coated orthodontic wires such as esthetic and their effectson reduced friction, corrosion and allergic reaction and the signifi cant consequences of plaque accumulation on oral health encouraged us to assess bacterial colonization on these wires. materials and methods: a total of 18 (9 upper and 9 lower) epoxy resin coated 16 × 22 nickeltitanium wires (spectra, gac...

Epoxy matrix are indispensable in the field of modern lightweight structures, such as indoor and outdoor pavements for floors, therefore many attempts made to improve quality these epoxy floors. In this work two types building waste materials, represented by coarse fine aggregate addition ground glass, were applied a top layer mixed with coating. Hand lay-up method was used prepare specimens, w...

Cathodic electrodeposition (CED) was used to coat the cast magnesium alloy Mg-9Al-1Zn-xRE with aluminum powder and epoxy. Immersion salt spray tests (ASTM B117) at room temperature for a total of 240 hours have been performed assess corrosion performances AZ91D alloy. At each 24-hour interval, samples were checked any damage or deterioration coating surface morphology. The X-ray diffraction (XR...

In this communication, a bis-silane prepolymer was used to modify epoxy resin, aiming enhance the corrosion resistance of coatings on aluminum alloy substrates. The prepared by tetraethoxysilane (TEOS) and γ-glycidoxypropyl trimethoxysilane (GPTMS). behavior silane-epoxy studied. Compared with silane monomer-modified coatings, bis-silane-modified have lower coating capacitance (Cc), higher char...

Polymer-clay nanocomposite coatings have attracted much attention because of impressive enhancements of coating properties. In this research, both commercially available and isophoronediamine-modified montmorillonite clays were used to obtain epoxy-clay nanocomposite coatings. These nanocomposite materials with different clay loadings in the form of coatings were applied to cold-rolled steel (C...

This review article describes the synthesis route of eugenol (4-Allyl-2-methoxyphenol, EU)-based resins, properties, and their use in coating application. EU-based resin is an attractive phenolic-based material with outstanding properties such as thermal stability, water-resistant, antioxidant, flame retardancy performance. However, limited research articles on resins have been published recent...

Abstract Corrosion and its protection are one of the major challenges that faced by industries. To overcome this, new coatings with characteristic properties which environmentally friendly introduced. A cost-effective most reliable way corrosion is via barrier coatings, in water-based epoxy showed significant resistance. Although coating creates a between metal corroding ions, there chance leak...
