Zinc, pigmented coatings

Another question is the proper technique for the evaluation of protective properties of zinc pigmented coatings. IMtll now, the most popular one is the test in a salt chamber (12.141. This technique does not allow a complete understanding of the complex phenomena oo-ouring in the coating. It seems that the impedance technique selected in this work provides more adequate and useful data. [Pg.230]

In the case of electrode B the oonductlve carbon black was used with the purpose to Influence the cathodic protection period. The modification C was made with zinc phosphate to Influence the second step In protective action of zinc pigmented coatings. [Pg.231]

It has been found that protective properties of zinc pigmented coatings can be enhanced b using zinc phosphate as an additive Influencing the performance of the coatings In the second stags of their protective action. [Pg.233]

Negative results have been obtained with oarbon black as an additive Intended to Improve protection properties of zinc pigmented coatings b Influencing the first stage of their protective action. [Pg.233]

The presence of strongly electronegative zinc-pigmented coating short circuits all local cell activity on steel. The steel becomes totally cathodic to the anodic zinc coating. The zinc corrodes, but the steel will not corrode even at bare spots, it is mandatory that the zinc coating be in electrical contact with the steel surface therefore, the steel must be stropped of all contamination. [Pg.92]

It was decided to carry out modifications of the highly zinc pigmented psdnt using the impedance technique to test the protective properties. Steel electrodes with the following coatings were tested ... [Pg.230]

Flake zinc pigments have a barrier effect and also act by a cathodic anticorrosive mechanism. Compared with zinc dust coatings, flake zinc pigments are formulated with lower pigment volume concentrations [5.178]. [Pg.209]

Another widespread application for flake zinc pigments is the coating of small articles with complex shapes (e.g., screws, steel springs, bolts, rivets) and for special anticorrosive paints (Section 5.2.11.1). [Pg.231]

These coatings give the most effective corrosion protection. They contain high volumes of zinc pigment and are exclusively used as primers. The steel is protected... [Pg.92]

Use Anticorrosive pigment for solvent-based epoxies and as auxiliary pigment for 1-package zinc-rich coatings. Also used in water-based coatings. [Pg.125]

The binder properties are useful in other pigmented coatings such as clay-based paints (119). The zinc-lithium silicate coatings can be applied by anodic electrodeposition on steel (120). In another-typc of use, lithium polysilicate provides an intermediate bond between the fluorocarbon polymer coating and metal on antisticking cook ware (121). [Pg.150]
