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.
