Duralac is a chromate containing jointing compound designed to inhibit electrolytic decomposition between dissimilar metals – often called galvanic corrosion. It is a single pack, air setting product. Used correctly, Duralac prevents anodic decomposition.
A newly developed version of Duralac called Duralac Green is now available. Duralac Green has an improved environmental footprint and exceeds standard Duralac in performance.
