Reduced corrosion with SoftAcid

SOFTACID TECHNICAL BULLETIN:  REDUCED CORROSION

SoftAcid has been found to be significantly less corrosive towards carbon steel and other metals than pure organic acids. This is because the aggressive nature of organic acids is reduced by the presence of lignosulfonic acid. With respect to corrosion, the dissociated lignosulfonic acid anions migrate towards the positively charged solid surfaces (such as concrete and steel) to form a protective layer.

SoftAcid is a range of products consisting of organic acids and modified lignosulfonic acids. The presence of the lignosulfonic acid gives the product its name “Soft”, due to its ability to moderate the aggressive nature of
the organic acids.
