Conclusions
Certain paint resins were able to inhibit the evolution of hydrogen of aluminium pigments in aqueous media at pH 10; especially drying alkyd resins showed excellent results. By contrast the two oil-free saturated polyesters examined were only very poor corrosion inhibitors at pH 10.
At a pH value of 8 all polyesters, alkyd resins, epoxy esters, phenolic resins, polyurethane and acrylic resins showed an almost complete inhibition of hydrogen evolution; the two polyesters were again (relatively) worst corrosion inhibitors at pH 8.
It can be supposed that the correct choice of paint resins may lead to the formulation of non-gassing water-borne metallic paints with unstabilized aluminium pigments.
