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.

Hamico® 8934 – Rinse Aid

Hamico® 8934 Rinse Aid is a stain preventing additive for rinse systems for use after hydrochloric or sulfuric acid pickling operations. It is an acidic product possessing corrosion protection and wetting. It is designed to eliminate the brown or reddish stains often experienced on steel exiting a continuous pickler. It eliminates the formation of iron hydroxide slimes which accumulate in rinse tanks as a result of acid bath carryover. Hamico® 8934 Rinse Aid is compatible with waste treatment processes where removal of metals like iron, copper, zinc, and chromium must be accomplished to meet limits for effluents.

This product prevents carryover products from depositing on the immersed steel surface and protects the rinsed surface before drying occurs. Hamico® 8934 Rinse Aid is low-foaming to make water treatment and disposal easier and employs a tracer to make it easy to make concentration determinations using a test kit.

Rainkote® NC – Stain Prevention Additive

Rainkote® NC is an additive to prevent line-stop stain in the rinse section of hydrochloric or sulfuric acid pickling lines. It is an acidic product possessing corrosion protection and wetting. It is designed to eliminate brown or reddish stains often experienced on the steel strip exiting a continuous pickler. It eliminates the formation of iron hydroxide slimes which accumulate in rinse tanks as a result of acid bath carryover.

Due to its non-chelating components, it is compatible with waste treatment processes where removal of metals like iron, copper, zinc, and chromium must be accomplished to meet limits for effluents.

Hamico® 8906-WT – Rinse Aid

Hamico® 8906-WT Rinse Aid is a stain preventing additive for rinse systems following hydrochloric or sulfuric acid pickling operations. It is an acidic product possessing corrosion protection and wetting. It is designed to eliminate the brown or reddish stains often experienced on steel exiting a continuous pickler. It eliminates the formation of iron hydroxide slimes which accumulate in rinse tanks as a result of acid bath carryover.

Hamico® Neutralizer 809-L

Hamico® Neutralizer 809-L is a combination of liquid alkalis and surface-active (wetting) agents designed specifically for neutralizing acidic residues from ferrous metals after pickling operations.
