Title

Oxygen Permeability as a Tool to Evaluate Coatings

Abstract

The results from oxygen permeability, moisture permeability and adhesion of coatings were compared with that of the accelerated salt spray tests as a means to gain information about the relationships of these factors to corrosion of brake cable parts used in automobiles. The corrosion protection correlates best with the oxygen permeability of the coatings. The oxygen permeability is roughly proportional to the corrosion rate. The moisture permeability is inversely proportional to the corrosion rate. No definable correlation between adhesion and corrosion protection was obtained for these coatings tested. The C-Resin is out of line with the rest of the coatings because it is an inorganic zinc rich coating which needs to be permeable to function.
