Activol® 1793-B is a sulfuric acid inhibitor for batch pickling. It is one of our strongest inhibitors, is a good “wetter” and provides a more uniform pickle and a better rinse. Additionally, it eliminates acid fumes and reduces hydrogen embrittlement. Pickle Life 1673-D (acid extender) and Activol® 1793-B can be used in combination to extend the life of the acid bath to iron levels of 7-12%. Activol® 1793-NF is a non-foaming version which can be used in operations utilizing combustion heating.
