The effect of a partial replacement spherical zinc particles by stainless steel flakes (SSF) on the corrosion protection performance zinc-rich epoxy (ZRE) coating was studied. Salt spray test, open circuit potential, electrochemical impedance spectroscopy and potentiodynamic polarization tests were utilized to evaluate anticorrosion coatings. results demonstrate that SSF enhanced properties ZRE...

Epoxy is extensively used for anti-corrosion coatings on metallic materials. Conventional epoxy have a permanent crosslink network that unable to repair itself when cracks and damages occur the coating layer. This study aims develop self-healing vitrimer/carbon nanotube (CNTs) nanocomposite coating. Two bio-based curing agents viz., cashew nut shell liquid (CNSL) citric acid (CA) were employed ...

Calcium phosphate was encapsulated into mesoporous silica nanoparticles (MSN). The effect of pH on the structure and morphology MSN release calcium from investigated. Epoxy coatings with (3 wt%) non-encapsulated wt% 5 were formulated their anti-corrosive performance evaluated by open circuit potential (OCP) electrochemical impedance spectroscopy (EIS) techniques. Results showed that encapsulati...

Bisphenol A (BPA) is a chemical agent used in the production of epoxy resins and polycarbonate plastic products, including water bottles, and as a coating for dental sealants, food/beverage containers, and canned food linings. Exposure to BPA has been linked to such negative health effects as obesity and heart disease. Concerns for the effects of BPA are greatest on infants and young children d...

The erosion-corrosion environments found in fluid conveying components such as pipelines, pumps, agitators and chutes have important implications for both service life and maintenance cost. The destructive synergy wrought when corrosion occurs in combination with erosion can be many times greater than the sum of each mechanism acting in isolation. A factory applied coating, if present, will hav...

Epoxy has been widely used as a coating material to protect the steel reinforcement in concrete structures, because of its outstanding processability, excellent chemical resistance, good electrical insulating properties, and strong adhesion/affinity. The major disadvantage raised from exothermic curing reaction highly crosslinked epoxy matrix is brittleness microcracks that change performances....

In the present study, Mg-Al layered double hydroxide (Mg-Al/LDH) was synthesized on surface of AZ31 Mg alloy substrate via in-situ hydrothermal treatment. Synthesis parameters were changed to determine their effect lateral size LDH. For this purpose, etching in nitric acid and anodizing sodium solution performed as pretreatments. Moreover, influence LDH pH (10 11) coating investigated. Morpholo...

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...

UV cured epoxy systems represent complementary technology to the established heat cured epoxy systems for coating, adhesion and encapsulation of electronic devices. The UV cured epoxy systems offer significant benefits in terms of fast cure and thus very short production cycle time; low stress and better colour due to room temperature cure; process wise no mix ratio problem or anhydride handlin...
