ECORR Systems offers Cortec® coating and fluid additives for manufacturers, formulators, water treatment professionals, metalworking operations, and industrial facilities seeking to incorporate corrosion protection into compatible coatings, cleaners, lubricants, coolants, process fluids, and water-based systems.

As an Authorized Cortec® Distributor, ECORR Systems helps customers select corrosion-inhibiting additives based on the carrier system, formulation chemistry, metal types, operating environment, application method, and required performance.

Add Corrosion Protection to Existing Formulations

Cortec® additives are designed to enhance compatible industrial formulations with contact corrosion inhibition, Vapor phase Corrosion Inhibitor protection, or a combination of both. They may be incorporated during product manufacturing or added to certain operating fluids in the field.

Depending on the formulation, an additive may help protect surfaces in direct contact with the treated fluid as well as metal surfaces above the fluid level, within enclosed headspaces, or inside recessed areas that conventional contact-only inhibitors may not reach.

Types of Cortec® Coating and Fluid Additives

Water-Based Formulation Additives

Water-soluble and water-dispersible corrosion inhibitors can be incorporated into compatible cleaners, coatings, metalworking fluids, process water, and other aqueous systems. Selected products offer low-foaming performance for spray, circulation, and automated applications.

Solvent-Based Coating Additives

Selected Cortec® additives can enhance corrosion and moisture resistance in compatible solvent-based coatings and certain waterborne systems. The additive must be evaluated for compatibility with the resin, solvent package, pigment system, drying characteristics, adhesion, and finished coating performance.

Metalworking Fluid Additives

Corrosion-inhibiting additives can be incorporated into compatible cutting fluids, grinding fluids, forming lubricants, cleaners, and in-process fluids. These additives may help protect workpieces, equipment, and metal surfaces between manufacturing operations.

Coolant and Heat-Transfer Fluid Additives

Cortec® offers additive technologies for compatible water- and glycol-based coolants and heat-transfer fluids. Selected formulations help protect ferrous and non-ferrous metals from corrosive contaminants in the liquid phase, vapor phase, and at fluid interfaces.

Oil and Lubricant Additives

Oil-compatible corrosion inhibitors can be added to selected hydraulic fluids, lubricating oils, circulating oils, preservation fluids, and other oil-based systems. Compatibility with the base oil and existing additive package must be confirmed before treatment.

Boiler and Condensate Additives

Cortec® boiler and condensate additives are available for compatible steam, condensate, and water-treatment programs. Product selection should account for operating pressure, temperature, water chemistry, metallurgy, downstream processes, and existing treatment chemicals.

Saltwater and Brine Additives

Specialized formulations are available for protecting compatible tanks, vessels, and equipment containing saltwater or brine. Selected products create a protective film near the waterline and on internal surfaces exposed as fluid levels rise and fall.

Fuel and Fuel-Oil Additives

Cortec® offers additives for selected fuel and fuel-oil applications. Depending on the product, these additives may provide corrosion protection, improve dispersion, or help manage sludge and deposits during operation or storage.

Contact and Vapor Phase Protection

Contact corrosion inhibitors protect metal surfaces directly reached by a coating or treated fluid. Vapor phase inhibitors migrate through an enclosed atmosphere and adsorb onto accessible metal surfaces above or outside the fluid level.

Combining these mechanisms can be useful in tanks, enclosed process equipment, coolant systems, storage vessels, packages, and machinery where fluid levels fluctuate or not every internal surface remains continuously wetted.

Additives Versus Finished Products

A corrosion inhibitor additive is normally intended to be incorporated into another formulation or operating fluid at a specified concentration. It may not be suitable for direct application as a stand-alone coating, cleaner, lubricant, or rust preventative.

Finished Cortec® products are supplied with their functional components already formulated and balanced for a defined use. Additives require additional compatibility testing, concentration control, mixing, and performance validation within the final formulation.

Benefits of Cortec® Coating and Fluid Additives

• Add corrosion protection to compatible industrial formulations
• Provide options for water-, glycol-, oil-, and solvent-based systems
• Support ferrous, non-ferrous, and multi-metal applications
• Offer contact and Vapor phase Corrosion Inhibitor protection
• Help protect enclosed headspaces and surfaces above fluid levels
• Support product formulation, process operation, maintenance, and preservation
• Provide concentrated treatment options for controlled dosing
• Allow corrosion control to be integrated into existing processes

Selecting the Correct Additive

Additive selection begins with the base formulation. Important factors include whether the system is water-, glycol-, oil-, or solvent-based; the resin or base-oil chemistry; pH; viscosity; temperature; foaming tolerance; metal types; and existing additives.

The intended function must also be defined. An additive selected for a cleaner may require different properties from one intended for a coating, hydraulic oil, coolant, boiler condensate, metalworking fluid, or storage tank.

Compatibility and Formulation Testing

An additive should not be introduced into a coating or fluid solely because it is compatible with the general carrier type. Laboratory testing should evaluate stability, separation, precipitation, viscosity, pH, foaming, drying, adhesion, appearance, corrosion protection, and other required performance characteristics.

Coating formulations may require testing for cure, hardness, gloss, film integrity, adhesion, water resistance, and topcoat compatibility. Fluid systems may require testing for filterability, seal compatibility, lubricity, thermal stability, microbial control, and interaction with the existing additive package.

Concentration and Mixing

Treatment concentration varies by product, formulation, operating environment, and required protection level. Adding too little may result in inadequate corrosion protection, while excessive concentration may affect product performance, increase cost, or create compatibility problems.

Follow the current Cortec® product data sheet for recommended concentration, mixing order, agitation, temperature, and incorporation procedure. Small-scale testing should be completed before full production or system treatment.

Metals and Materials to Evaluate

Identify every metal and non-metal material that may contact the final formulation, including:

• Carbon and stainless steel
• Cast iron and galvanized steel
• Aluminum and magnesium alloys
• Copper, brass, and bronze
• Coated and plated surfaces
• Plastics, elastomers, seals, and gaskets
• Filters, membranes, and absorbent materials

Multi-metal protection claims and material compatibility vary by product and should be verified through current technical documentation and application testing.

FAQ

What is a coating or fluid additive?

A coating or fluid additive is a concentrated component incorporated into another formulation or operating fluid to add or improve a specific property, such as corrosion protection, scale control, deposit management, or vapor phase protection.

Can Cortec® additives be added to any coating?

No. Additive compatibility depends on the coating’s resin, solvent, pigments, pH, cure mechanism, and other components. Laboratory formulation and performance testing should be completed before production use.

Can an additive be used as a finished corrosion preventative?

Not unless the product documentation specifically permits direct use. Many additives are concentrated formulation components and must be incorporated at a recommended concentration into a compatible carrier.

Do Cortec® additives protect multiple metals?

Many formulations are designed for multi-metal protection, but compatibility varies. All metals and alloys in the system should be identified before product selection and testing.

What is the difference between contact and vapor phase protection?

Contact inhibitors protect metal reached by the treated coating or fluid. Vapor phase inhibitors migrate through enclosed airspaces and help protect accessible surfaces above the liquid level or beyond direct coating contact.

How is the correct additive concentration determined?

Concentration depends on the additive, base formulation, metal types, operating conditions, exposure period, and required performance. Follow the current technical data sheet and validate the concentration through testing.

Will a corrosion inhibitor affect other formulation properties?

It may. Additives can affect stability, viscosity, pH, foam, appearance, cure, adhesion, lubricity, filterability, or other characteristics. This is why small-scale formulation and performance testing are important.

Can Cortec® create or support a custom formulation?

Product availability and formulation support depend on the application, volume, technical requirements, and manufacturing feasibility. ECORR Systems can help collect the necessary information and coordinate product guidance.

Can ECORR Systems help select the correct additive?

Yes. ECORR Systems can review the carrier system, existing formulation, metal types, operating conditions, concentration requirements, and performance objectives to help identify an appropriate Cortec® additive for evaluation.
