Hamico® 8936 – Rinse Aid

Hamico® 8936 Rinse Aid is an additive for rinse systems after pickling steel using hydrochloric or sulfuric acids. Hamico® 8936 Rinse Aid prevents the formation of iron hydroxide slimes which typically occur in rinse tanks and prevents surface discoloration on steel exiting the bath. Hamico® 8936 Rinse Aid complexes ferrous iron, thus preventing it from re-depositing.

Hamico® 8936 Rinse Aid buffers the rinse water against sudden drops in pH, due to acid carryover from pickling tanks and protects from flash rusting after rinse operations. It may be used in hot or cold baths.

Hamico® 8936 Rinse Aid is easy to handle and is not corrosive to the skin.
