Mineral Acid Corrosion: Inhibitors for HCl, Sulphuric, Sulfamic, and Organic Acids
HCl Acid Inhibitor
Hydrochloric acid corrosion inhibitors are specifically formulated to mitigate the corrosive effects of HCl during acid cleaning or pickling processes. Comprising a synergistic blend of surfactants, solvents, and dispersants, these chemicals offer corrosion protection in hydrochloric acid baths, particularly at high temperatures.
Operating by diminishing the corrosive impact of hydrochloric acid on metallic surfaces, these inhibitors function through diffusion from the bulk solution to the metal surface. Upon reaching the metal surface, they adsorb, forming a protective film that effectively limits the direct contact of the acid with the underlying base metal. This protective mechanism ensures enhanced durability and longevity of metal equipment in corrosive environments.
Sulphuric Acid Inhibitor
Sulphuric Acid Inhibitor functions as a uniquely formulated additive in various industrial processes involving sulphuric acid etching. These chemicals create a protective film on metals and alloys, including silicon steel, guarding against the corrosive effects of acid etching.
In chemical streams, these additives serve two purposes—preventing and reducing corrosion. By lowering the corrosion rate, they contribute to extending the overall service life of equipment. The utilization of H2SO4 inhibitors proves cost-effective for preventing or managing corrosion in corrosive environments, enabling the use of less expensive metals without compromising durability.

Organic Acid Corrosion
Specifically formulated additive in various industrial processes involving sulphuric acid etching is the Sulphuric Acid Inhibitor. This additive generates a protective film on metals and alloys, including silicon steel, effectively guarding against the corrosive effects of acid etching.
Within chemical streams, these additives undertake two primary roles. They not only prevent corrosion but also contribute to the reduction of corrosion rates. This dual functionality synergistically works towards extending the overall service life of the equipment.
The utilization of H2SO4 inhibitors establishes a cost-effective strategy for preventing or managing corrosion in corrosive environments. This approach facilitates the use of less expensive metals without compromising on durability.
Organic Acid Inhibitor
Organic Acid Corrosion Inhibitors are widely used in industry because of their effectiveness at wide range of temperatures, compatibility with protected materials, and good solubility in water, low costs and relatively low toxicity. Organic corrosion inhibitors adsorb on the surface to form protective film which displace water and protect it against deteriorating. Effective organic corrosion inhibitors contain nitrogen, oxygen, sulphur and phosphorus with lone electron pairs as well can contain structural moieties with pi-electrons that interact with metal favouring this adsorption process.
Key Features and Benefits
- Extends system metal life
- Saves power and increases heat transfer efficiency
- Increases glycol life by reducing oxidation
- Does not affect freeze protection properties of the coolant running
- Does not form sludge deposits inside the system
- Avoids leakage and minimizes maintenance jobs
- Avoids batch losses otherwise due to PHE leakages
Sulfamic Acid Inhibitor
Sulfamic Acid Inhibitor is a multi-acid corrosion inhibitor based on diethyl thiourea, stabilizers and surfactants. This formulation is semi foaming acidic corrosion inhibitor that is utilised as pre-formulated descalant. Suitable for metals such as Copper, Brass, Nickel, Tin, Lead, Zinc, galvanized surfaces and all type of steel. Get quote for Acid Corrosion Inhibitors for Sulfamic Acid and Sodium Bisulfate below.
