Acid Inhibitors are formulated chemistries that help in the prevention of acid attack on metallurgy without hampering the acidic effect or in some occasions even enhancing the acid effect in the given process or application. Acid inhibitors, in terms of metal manufacturing and handling can also be called acid corrosion inhibitors, rust preventatives or rust preventives.In essence, these are products (usually liquids) are used to permit:
  • Long or short term storage of metals and alloys
  • Safe handling between production processes
  • Protection from environmental variables such as temperature and humidity
These chemical additives are applied by dip, spray or other coating methods to help in the protection of metal components and equipment from the corrosive action of a direct contact or environmental acid. The concentration and type of acid inhibitor needed is determined by the type of metal that needs to be protected and the conditions experienced by the metal. The various types of acid inhibitors offered by Chemtex Speciality Limited are - Hydrochloric acid inhibitor, sulfuric acid inhibitor, sulfamic acid inhibitor, citric acid inhibitor etc. Chemtex Speciality Limited is an ISO 9001, ISO 14001 and OHSAS 18001 certified manufacturer and supplier of Acid Inhibitors. We have been in this field of chemicals for over a period of 40 years and we will continue to extend our services towards enriching the circadian operations of other industrial sectors.

Heavy metal industries undergo acid cleaning or 'pickling' for removal of rust, scale deposits from metal surfaces such as Iron, Copper, Tin, Nickel, Aluminium, Zinc and even galvanized surfaces. The most common acid used in this phenomenon is Hydrochloric Acid which is strong as well as corrosive. To nullify the corrosive action of HCl, Acid Inhibitor is used. Chemtex's HCl acid inhibitors, when dosed along, effectively removes dust, dirt, oily, greasy and other carboneceous deposits from metal surfaces without taking part in any type of corrosive reaction. The working mechanism involves two important process, Bulk Diffusion and Adsorption. It gets adsorbed on to metal surface, forming a protective coating and prevents corrosive agents to react with metal ions.

Key Features and Benefits:
  • Blend of organic solvents, surfactants and dispersants
  • Does not have adverse effect on metal surfaces
  • Fume suppressant
  • Well compatible with almost all type of metal, including copper and brass alloys
  • Cost effective dosage
