Reduced corrosion with SoftAcid


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 lignosulphonic acid. With respect to corrosion, the dissociated lignosulphonic 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 lignosulphonic acids. The presence of the lignosulphonic acid gives the product its name “Soft”, due to its ability to moderate the aggressive nature of
the organic acids.
