Various types of zinc-rich coatings are available for corrosion protection. The challenges associated with the proper specification and application of zinc-rich coatings are briefly discussed. The paper then focuses on data from various studies, which quantify the corrosion protection benefits of various types of zinc-rich coatings. ZINC RICH COATING TECHNOLOGIES Zinc-rich coatings are used by ...

in recent years many research works have been carried out on anti-corrosive nanocomposites coatings containing mineral reinforcements. the most important criteria in these attempts are polymerization method and the type of matrix and reinforcement of nanocomposites. in this regard, the physical and mechanical properties of the polymers in which a small amount of filler is used can be improved. ...

Low-temperature solution processible and solventless silica-epoxy hybrid materials composed of organically modified silica nanoparticles and epoxy monomers were successfully fabricated through simple sol-gel process and solvent evaporation. These silica-epoxy hybrid materials exhibited the homogeneous dispersion without any phase separation, aggregation, and gelation in the solventless environm...

ing operations involvig the use of a bisphenol-A diglycidyl ether tye of epoxy resin. ln a faciity producig miltaiy aircraft, the use of an epoxy prier did not result in detectable epoxide levels, and the authors surmised that the epoxy-amine curig reaction had probably . consumed most of the epoxide group. Epoxide levels of 2-12 J.Eq/m3 epode functional group were recorded durig the painting o...

In this paper, electrochemical behavior of epoxy paints embedded by modified calcium carbonate particles was investigated during exposure to 3.5 wt% NaCl solution. The precipitated calcium carbonate (PCC) and ground calcium carbonate (GCC) particles were utilized as inexpensive filler for epoxy paints. Electrochemical impedance spectroscopy (EIS), polarization tests and pin-on-disk method w...

In this research, graphene oxide (GO) nanoparticles were modified by second and fourth generations of poly(amidoamine) dendrimers in order to improve the particle dispersion quality in the epoxy matrix and therefore its barrier anti-corrosion performance. Confirmation on the GO surface modification by Polyamidoamine generation 2 (PAMAM2) and polyamidoamin generation 4 (PAMAM4) was carried o...

Adhesion strength of exterior or interior coating of steel pipes is too important. Increasing of coating adhesion on surfaces can increase the life time of coating, safety factor of transmitting line pipe and decreasing the rate of corrosion and costs. Preparation of steel pipe surfaces before doing the coating process is done by shot and grit blasting. This is a mechanical way to do it. Some e...

Properties of concrete can be improved using different coating materials and chemicals. Some the materials, however, are not effective as there is a weak bond between coarse aggregate cement mortar. Hence, in this research, mechanical dynamic properties with epoxy resin, epoxy-sand silicon coated aggregates at volume fractions ranging from 5 to 15 percent were experimentally investigated. The t...
