Acid Inhibitors-Rinse Aids-Acid Additives

Activol® Acid Inhibitors


  • Provides a high degree of restraining action to the attack of hydrochloric acid on base steel. Inhibition values typically increase from 92% as inhibitor concentration is raised from 1/16% to 1/2%.
  • Does not retard the descaling rate of oxides on steel surfaces.
  • Wetting properties allow a uniformly pickled surface, free from smut or ingrained scale.
  • Creates uniformly pickled metal surfaces with a shiny surface and minimal edge corrosion.
  • Reduced hydrogen evolution at the solution/steel interface reduces hydrogen embrittlment.
  • Pleasant odor facilities manual addition.
  • Stable in pickling solutions for extended time periods at elevated temperatures without losing inhibiting action.

Other Benefits

Other benefits that come with the introduction of Activol® 1803 as an acid additive:
  • Uniform, brighter pickled surface, free of smut or ingrained scale
  • Easily rinsed
  • Prevents hydrogen embrittlement
  • Reduces acid fumes
  • Reduced overall production cost

Customer Experience

A major producer of high quality steel sheet was looking for increased efficiency in its pickling operation. The company was already using an acid inhibitor and believed that better inhibitor technology could decrease acid consumption, lower total costs and improve product quality.

The introduction of Activol® 1803 resulted in savings in Acid consumption 194,000 gallons per year/$70,000 per year.

Hamico® Rinse Aids


Hamico® 8906-WT prevents carryover products from depositing on the immersed steel surface. It also protects the rinsed surface after it exits the rinse section and before it dries. It ensures good wetting on the metal surface and is low-foaming, minimizing disposal and water treatment issues. Hamico® 8906-WT eliminates brown or reddish line stop stains that can form on steel as it exits from a continuous pickling line. It also prevents iron hydroxide slimes from forming in rinse tanks as a result of acid bath carryover.

Acid Additives

Boilers and Industrial Equipment Cleaning

When you are cleaning boilers, heat exchangers, paper mill digesters, and other high-investment pieces of equipment in your facility, you want them to be protected from corrosion during the process. We offer Potentol® 2803 and Potentol® 2804.

Process & Equipment Information

Acid may be pre-inhibited by the supplier, added upon delivery, or metered in to the pickle line. Consult your HMC technical representative to discuss the best method for your operation, or to recommend accurate and reliable product metering equipment for your pickle line.
