Improvement of electrochemical action of zinc-rich paints by addition of nanoparticulate zinc

Anticorrosion efficiency of zinc-filled epoxy coatings containing conducting polymers and pigments

“…A very compact and perfectly adhering barrier layer that is highly resistant to normal atmospheric effects emerges. This represents active protection because the function of electrochemical cathodic protection is renewed after each instance of mechanical damage to the film [1,5]. Zinc oxide and zinc hydroxide also possess some anticorrosion properties [6].…”

“…electrochemical role of zinc in the zinc-steel cells. The zinc oxide content of the film can be up to 20% without degrading its protection efficiency, owing to a certain conductivity of the zinc oxide [1,5].…”

Eco‐friendly, acrylic resin‐modified potassium silicate as water‐based vehicle for anticorrosive zinc‐rich primers

“…20 The degree of blister in near section areas of coatings increases according to the following order C3 < C2 < B2 < B3 < A5 < B1 < C1.…”

Hybrid Zinc-Rich Paint Coatings

“…There were some works aiming to characterize liquid ZRPs, 2 working out their modeling by means of electrochemical impedance spectroscopy (EIS), 2,3 analyzing the duration of active-passive protection terms 4 andpretreatment of the surface of steel substrate rust converter 5 and investigating the influence of salt contamination of the interface, 6 pointing out the difference between the early-stage and later-stage diffusions of zinc and iron corrosion products impacting the overall protection performance. A number of studies have disclosed the effects of pigment volume concentration (PVC), 7-12 the zinc grain size range from microns to the nanometer range [12][13][14][15][16][17] or the spherical and lamellar 8,10,18 shape 8,18-20 of the pigments. Nonetheless, a combination of the spherical and lamellar pigments gives the best performance.…”
