Armohib® 31 is a thiourea corrosion inhibitor that is used on metal equipment and surfaces that are acid cleaned to prevent the formation of rust.
Armohib® 31 is a quaternary dibutylthiourea salt that is ideally suited to inhibit corrosion caused by acid cleaning. In meat and poultry packing plants metal equipment is often acid cleaned. Acid corrosion inhibitors need to be included in the cleaning formulation to prevent the corrosion of expensive packing equipment. Armohib® 31 is acceptable for use in acid cleaners by the USDA and helps to protect metal equipment during acid cleaning.
