Abstract:
A rust conversion composition comprises the reaction product of a polyhydroxybenzoic acid and a alkane polyol, in admixture with a film forming polymer, and water. The composition is applied to rusted, iron-containing surface, and allowed to dry to form a hard, moisture and corrosion resistant film. Alternatively, the film may be removed to produce an iron-containing surface free of rust.
