... water based epoxy dispersion INTRODUCTION Graphene was first isolated in 2004 by Andre Geim and Konstantin Novoselov at Manchester University. They used sticky tape to remove single layers from the surface of graphite and deposit them on a silicon wafer. The isolation of graphene was a breakthrough...

... thicknesses, aging times and CP conditions. Steel substrate tests Abstract It has been hypothesized that fusion bonded epoxy (FBE) could be partially permeable to cathodic protection (CP, producing an imbalance between cathodic and anodic reactions and inducing a high pH environment within disbonded areas...

... contact angles (WCA) of the first six seconds were estimated and presented in Figure 5 . From the measurements, it is understood that coatings used are hydrophilic, as the contact angles are less than 90°. However, MC coatings are found to be relatively more hydrophobic compared to epoxy coating (EPX...

... will compare adhesion of two coatings to different substrate surface conditions while both coatings will be cured in two different environments. Our goal is to investigate the effect of curing environment of coatings on adhesion to the substrate. splash zone immersion coating epoxy underwater cure...

... through defect free coatings has shed a new light on the topic. It has been found that most of the commercial pipeline coatings tested in unaged conditions present a CP shielding behavior. Accelerated hydrothermal ageing of fusion-bonded epoxy (FBE) coatings was performed to study the effect of water...

... by which GNPs work as anti-corrosive pigments and investigate synergistic effects which will allow improvements in coatings anti-corrosive performance. Electrochemical AC impedance Spectroscopy (EIS) and corrosion potential (OCP) measurements has been used to probe the properties of GNP-epoxy coatings...

... requirements for coatings, pull-off adhesion strength plays a great role. Based off of various performance requirements for protective coatings the general guidance is that there is to be no adhesive failure between the first coat fusion bonded epoxy (FBE), field joint coating, or ARO and the substrate (steel...

... of concrete protective coatings and cathodic protection techniques. In this context, dual-coated (zinc/epoxy) rebars have been widely used in various countries with very promising results. In Brazil, the use of coated rebars is incipient, summarized in some use of galvanized bars in special concrete...

... on a multitude of factors. Abstract Composite repair systems composed of carbon fiber/epoxy composite materials can be affected by exposure to harsh environments. The vast majority of testing on composite repair systems to date has been to investigate the effects of high temperatures on composite performance...
