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....

The article discusses the results of a study on development effective compositions anticorrosive composite polymer materials and coatings filled with organic-mineral ingredients based epoxy resins ED-16 ED-20. developed main physical-chemical mechanical properties oligomers other are given.

The effect of hydrophilic nanosilica additions on the (1–3% by wt.) mechanical performance epoxy powder coatings after UV exposure was investigated in this study. were prepared mixing a commercial with nanoparticles hot mixer, an alternative method that is simpler than extrusion. Powders electrostatically applied carbon steel and cured to obtain coatings. epoxy-based exposed xenon lamp irradian...

Oil and Gas pipelines are protected by various types of external coatings in conjunction with CP systems. Polyethylene is commonly used as the top coat in two or three layer systems. The existing two layer system found in the North American and Australian markets uses an adhesive that is mastic-based. It provides excellent corrosion resistant properties and has relatively low shear resistance i...

The cathodic delamination and wear resistance of epoxy powder coatings were evaluated after adding 3 % (by wt.) calcium ion exchanged micropigments from amorphous synthetic silica. materials manufactured through the innovative economical hot mixing method, three different considered: commercial epoxy, without submitted to treatment, with micropigments. curing kinetics was studied in order evalu...
