RODINE Acid Corrosion Inhibitor

Chemtex Speciality Limited is a public limited organization involved in the manufacturing of a various range of Performance Chemicals. Among these, Acid Corrosion Inhibitor stands out to be an effective and most used product that Chemtex manufactures under the trade name of Rodine.

Let us first understand the role of Acid Corrosion Inhibitors

Acid Corrosion Inhibitors• Corrosion is a well known phenomenon in the industrial sector

• Generally affected by the water characteristics, metal used, etc.

• Corrosion is a result from water with low pH level where H+

concentration seems to be very high to react with the electrons of the cathodes and thus, the problem of corrosion increases.

• Metal parts get dipped in acid baths for removal of rust and scale and for providing protection to base metal

Now, this acid treatment is the cause for another main concern of the industries

Acid Corrosion Inhibitors• Acidic Corrosion wears away material gradually mainly by acidic

compounds

• Acidic Corrosion is an electrochemical process which is influenced by the diffusion of moisture, oxygen, and presence of acidic pollutant on the metal surfaces

• This leads to the requirement of acid inhibitors to help in limiting the acid attack on base metal, thereby helping in reducing the economic loss for the industry

• Acid Corrosion Inhibitor formulated by Chemtex Speciality Limited, are designed for the prevention of attack due to acidic components present in the environment, on the metal components without disturbing the acidic effect

RODINE – Products and their role in inhibiting acidic

corrosion

RODINE• Rodine range of products serves as the worldwide

standard for acid inhibitors

• Rodine inhibitors have been formulated to provide effective protection to base metals from acidic corrosion

• Helps in reducing iron build-up

• Aids in eliminating chances of over pickling

• Accounts for better finish and appearance

RODINE• Helps in improved protection of equipments

• Rodine range of products include inhibitors that are designed for use in most acid cleaning operations without affecting the productivity

• Finds application in the following industries: Iron & Steel, Power Station, Petrochemical &

Refineries, Heavy Engineering Industries, Cement, Glass & Ceramic Industries, Sugar Processing Industry, Miscelleneous Manufacturing Industry, etc.

Range of Products

RODINE 213• Rodine 213 is an organic liquid inhibitor specially

formulated to prevent acidic attack on metal surfaces.

• Aids in prevention of acidic attack from hydrochloric acid on iron and steel surfaces, copper and brass surfaces during cleaning and pickling operations

• Effectively disperses greasy deposits and proves to be best for pickling prior to plating

• Cleaning action can be enhanced if the equipments with the inhibited acid solution can be heated

• Rodine 213 provides a considerable safety in relation to acid strength, temperature and time.

RODINE 103• Rodine 103 serves as an effective inhibitor for phosphoric, sulfuric,

hydrochloric, acetic, oxalic, citric, bisulfate, sulfamic and other organic acids.

• Designed specifically to be used in industrial cleaning operations for preventing acid attack on copper, brass, mild steel and stainless steel.

• Aids in enriching strength of pickling acid bath and reduces acid consumption

• Heating of acids or equipments can be done to speed up the operation prior to cleaning

• The factors that contribute to an efficient cleaning by Rodine 103 depends on the acid being used, temperature of the cleaning bath and the type of metal surface of the equipments.

RODINE 31A• Rodine 31A serves as an acid inhibitor for organic

acid

• Provides protection to brass, steel and copper against the attack of sulfuric, phosphoric, sulfamic, formic acid, acetic oxalic acid, citric acid, bisulfate solution and mixtures thereof and conditionally for hydrochloric acid

• It imparts excellent pickling and modifies the metal surface to aid in the prevention of corrosion.

• Rodine 31A presents itself as a chloride free inhibitor

RODINE 95• Rodine 95 serves as a Phosphoric Acid Corrosion Inhibitor

• When added to aqueous solutions of Phosphoric Acid helps in providing protection to the metal surface during cleaning and descaling applications

• Enhanced metal protection and wetting properties exhibited by it helps in providing efficient cleaning performance

• The concentration of the acid inhibitor used is generally derived by the type and properties of the metal to be protected and the conditions under which the metal is to be treated.

RODINE 85• Rodine 85 serves as an acid Inhibitor for Sulfuric Acid

• Serves as a non-foaming acid corrosion inhibitor

• Designed specially for preventing the acid attack of sulfuric acid (of all concentration) on various metals such as Brass, Copper, Nickel and all types of steel

• Aids in achieving maximum cleanliness on nickel work and being a strong inhibitor with detergent helps in improving the rinsability

• Inhibitor creates a protective film over silicon, steel and alloys from acid.

RODINE 52• Rodine 52 serves as a Hydrochloric Acid Inhibitor

• It is an acidic blend of alkoxylated fatty polyamines, propargyl alcohol, Butanol, formaldehyde and defoamer

• Non- foaming acidic inhibitor for use in acid pickling, cleaning and oil well acidization

• Designed to prevent the acidic attack of Hydrochloric acid (of all concentration) on various metals such as Copper, Brass, Nickel, Tin, Lead, Zinc, Galvanized surface and all type of steel.

RODINE 51• Rodine 51 is a low pH liquid inhibitor for different acid such

as hydrofluoric, hydrochloric, sulphuric, phosphoric acid

• Formulation is based on substituted triazine, propargyl alcohol and diethylthiourea

• It is a strong HF cleaning grade acid inhibitor with semi-foaming nature

• Effective for metals such as copper, brass, nickel, and all types of steel.

• It serves as a medium strength inhibitor that can be applied for batch pickling as well as continuous strip pickling.

RODINE 50• Rodine 50 serves as a Hydrochloric Acid pickling inhibitor

• It is a medium strength, liquid, non-foaming inhibitor that gives good pickling performance prior to electroplating

• Effective for metals such as brass, nickel, copper and all types of steel and modifies the metal surface to aid in preventing corrosion

• Provide average inhibition efficiency of 97% or more and shows stability in concentrated acid for periods of time

• Formulated particularly to be used in conventional hydrochloric acid cleaning or pickling operations on unreactive and mild steel

RODINE range of acid corrosion inhibitors are formulated to inhibit different groups of

acids and are available in various compositions and pack sizes to suit different

industrial applications
