Water-soluble corrosion inhibitors
We offer a wide selection of water-soluble corrosion inhibitors suitable for use in neutral to moderately alkaline systems. Our inhibitors are based on a variety of chemistries such as amine and alkali carboxylates, phosphate esters, borates, and amphoterics. Most are low foaming and used to protect metals in applications such as metalworking fluids, metal cleaning, coolants, aerosols, and water-based systems where little-to-no foam is essential.
Our corrosion inhibitors are also multifunctional. Many exhibit detergency, hydrotroping, and wetting properties along with the ability to protect a variety of metals including aluminum, steel, and yellow metals such as copper and brass.

DeCORE AFCI-45
A multifunctional, low foaming, amine-free, corrosion inhibitor used to protect a variety of metals including aluminum, copper, brass, bronze, steel, cast iron, ferrous, and non-ferrous metals in aqueous systems (~pH 7-10). It can also prevent flash rusting of steel in mildly acidic systems (pH ~3 -5).
Independent laboratory testing was conducted in duplicate under ASTM D-1384, Corrosion Test for Engine Coolants in Glassware. Test results confirm that this inhibitor is an excellent candidate for evaluation in glycol-based engine coolants.
This powerful inhibitor is also an excellent hydrotrope for nonionic surfactants in the presence of commonly used detergent builders and other alkaline electrolytes.
DeCORE AFCI-45 does not contain amines, nitrites, chromates, phosphates, borates, or azole chemistries.
DeCORE APCI-95MOD
A low foaming, 100% active, mixed-amine carboxylate recommended for use in neutral or moderately alkaline water-based formulations. Very effective all-purpose corrosion inhibitor suitable for use on soft metals such as copper and brass. Also effective on aluminum, cast iron, steel, galvanized steel, and other ferrous and non-ferrous metals. Suitable for use in synthetic cutting fluids, metal cleaners, aerosol products, water-based paints, and cooling tower additives. Does not contain nitrites, chromates, phosphates, or borates.
DeCORE IMT-100LF
A low foaming, 100% active, mixed-amine carboxylate for use in moderately alkaline systems. Effective at low concentrations in both ferrous and non-ferrous applications. Effective in high chloride environments and at elevated temperature. DeCORE IMT-100LF also contributes lubricating, wetting, and spreading properties. Does not contain nitrites, chromates, phosphates, borates, or azole chemistries.
DeCORE IDMT-100
A 100% active, water-soluble, mixed-amine carboxylate effective as a multi-metal corrosion inhibitor. Recommended for use in moderately alkaline systems at low levels (0.25% – 0.5%) to protect a variety of metals including aluminum, copper, brass, bronze, steel, cast iron, ferrous and non-ferrous metals. Does not contain nitrites, chromates, phosphates, borates, or azole chemistries.
DeTROPE CA-100 & DeTROPE CA-90
DeTROPE CA-100 is an outstanding hydrotrope and an excellent corrosion inhibitor for aluminum and ferrous metals. It is 100% active, effective at low concentrations, and will not leave a solid or waxy residue on metal surfaces upon drying. The corrosion inhibition and hydrotropic properties of DeTROPE CA-100 are complemented by good wetting properties. Recommended for use in moderately alkaline systems. Free of nitrites, phosphates, borates, and azole chemistries. An easier-to-handle, 90% active version is available as DeTROPE CA-90 that remains liquid at low temperatures (~35°F-40°F). Both products exhibit low, quick-breaking foam.
DeCORE BE Amine Borate Corrosion Inhibitors
DeCORE BE amine borates are water-soluble, non-foaming corrosion inhibitors effective on ferrous and non-ferrous metals in neutral to mildly alkaline systems, including aerosol formulations. They are very effective corrosion inhibitors when used at concentrations of 0.5% – 1% by weight, and suggested for use in aqueous, alkaline systems where zero foam is required. Amine borates will prevent corrosion on aluminum but may cause staining. Both DeCORE BE (100% active) and DeCORE BE-85 (85% active) are mixtures of MEA-borate and MIPA-borate but in differing ratios. DeCORE BE has a considerably higher Alkali Value (570-600) vs. DeCORE BE-85 (415 – 435). These products do not contain nitrites, chromates, phosphates, or azole chemistries.
ENVIRONMENTALLY SAFER CORROSION INHIBITORS
The following corrosion inhibitors do not contain amines, phosphates, nitrites, azoles, or boron. All products are non-phenolic and readily biodegradable.
DeCORE AFCI-45
A multifunctional, low foaming, amine-free, corrosion inhibitor recommended to protect a variety of metals including aluminum, copper, brass, bronze, steel, cast iron, ferrous and non-ferrous metals in aqueous systems (~pH 7-10). It can also prevent flash rusting of steel in mildly acidic systems (pH ~3 -5). This powerful inhibitor is also an excellent hydrotrope for nonionic surfactants in the presence of commonly used detergent builders and other alkaline electrolytes.
DeCORE SCI-45ECO
A low foaming, water-soluble corrosion inhibitor suggested for use in metal process cleaners and other metalworking products for prevention of rust on steel and cast iron. It also provides limited, short term corrosion inhibition on brass, copper and other non-ferrous metals. Not recommended for use on aluminum.
DeTERIC LP: CORROSION INHIBITOR FOR ACID SYSTEMS
DeTERIC LP, sodium lauriminodipropionate, is a multifunctional, high foaming amphoteric surfactant offering corrosion inhibition properties in strong acid systems and in hard water. Recommended for use in metal process cleaners, automotive and transportation applications, HI&I cleaners such as acidic bathroom cleaners, grout cleaners, and other acidic applications where prevention of rust on steel is desired. This amphoteric also provides limited, short term protection on aluminum in acidic environments, and is an effective corrosion inhibitor in hard water environments.
