"Corrosion protection is better with galvanized steel than with untreated steel. A new Zn-Co galvanization [sic] alloy was evaluated in salt spray cabinet in an accelerated test for corrosion resistance according to ASTM method B 117-73. The Zn-Co alloy treated brake cable parts painted with seven different industrial coatings were exposed in the salt spray cabinet. The oxygen permeability, moisture permeability and adhesion of these coatings were compared with the accelerated salt spray test to gain information about the relationships of these factors to the corrosion of brake cable parts used in automobiles. The results showed a strong correlation between oxygen permeability of the coatings and the corrosion resistance of the substrates. One of these coatings provided over three thousand hours protection in the salt spray chamber.
An epoxy coating was used with and without the Z-6020 silane coupling agent to see if the silane coupling agent improved the adhesion of a given epoxy system. The epoxy coatings were evaluated according to a peel test method and the silane gave a slight improvement in adhesion in this epoxy system"--Abstract, page iii.
