Abstract
The invention is related to a composition destined to protect steels against corrosion by utilization of the own steel rust as passivating element, the rust being removed from the steel and/or being synthetically prepared and agglutinated with a resin, where the resin can have or can not have as a electric conductivity promoter material an intrinsically conductor polymer (ICP), in this case polyaniline, in its conducting form (emeraldine salt) or non conducting (emeraldine base), besides load(s) and a dispersant oil.
Claims15
Composition destined to be applied on steels for protection of their surfaces against corrosion, comprising from 45 to 60% by weight of a rust which is the own natural rust of steel or a synthetically prepared rust with the same chemical composition of the referred natural rust, from 35 to 45% by weight of an agglutinant, from 2 to 10% of polyaniline, from 2 to 5% of load and from 0.5 to 2% of dispersant oil.
