Cortec® VpCI® Metalworking Products

ECORR Systems provides Cortec® VpCI® metalworking products for machining, cutting, grinding, forming, stamping, cleaning, in-process handling, parts storage, and finished-product shipment.

As an Authorized Cortec® Distributor, ECORR Systems offers metalworking fluids, coolant and lubricant concentrates, corrosion-inhibiting additives, rust preventatives, cleaners, and preservation products for ferrous and non-ferrous metals throughout the manufacturing process.

Corrosion Control Throughout the Metalworking Process

Metal parts can begin corroding at nearly any stage of production. Water-based fluids, machining residues, fingerprints, metal fines, humidity, condensation, wash operations, and delays between manufacturing steps can leave freshly worked surfaces vulnerable to rust, staining, and oxidation.

Cortec® metalworking products help manufacturers combine machining performance with corrosion protection during production, temporary storage, and shipment. Depending on the formulation, these products may provide lubrication, cooling, cleaning, water displacement, contact corrosion inhibition, or Vapor phase Corrosion Inhibitor protection.

Common Metalworking Applications

• Cutting, turning, drilling, and milling
• Grinding, boring, broaching, and gear cutting
• Metal stamping, drawing, and forming
• Wet tempering of galvanized and cold-rolled steel
• Tube, pipe, wire, and coil production
• Machined parts and precision components
• Castings, forgings, and fabricated assemblies
• Parts washing and post-process rinsing
• Hydrostatic testing and equipment preservation
• In-process parts staging and work-in-progress storage
• Finished-part storage and export shipment
• Machine tools, tooling, dies, fixtures, and work surfaces

Types of Cortec® Metalworking Products

Cutting and Machining Fluids

Cortec® cutting and machining fluids provide lubrication and cooling during metalworking operations while helping protect freshly machined surfaces from corrosion. Products are available for light-duty and selected demanding cutting, grinding, milling, turning, drilling, and forming operations.

Metalworking Lubricants

Water-based, semi-synthetic, oil-based, and biobased lubricants are available for stamping, drawing, tempering, forming, machining, and other operations where friction, tool wear, surface quality, and corrosion protection must be managed.

Corrosion-Inhibiting Additives

Cortec® additives can enhance compatible soluble oils, synthetic cutting fluids, hydraulic oils, lubricants, process fluids, and water-based systems. Additive selection should be based on the fluid chemistry, metal types, operating conditions, concentration, and required corrosion protection.

In-Process Rust Preventatives

In-process rust preventatives protect parts between manufacturing stages, during temporary storage, and before final packaging. Depending on the product, protection may be provided by a dry, oily, wax-like, or nearly invisible film.

Water-Displacing Products

Water-displacing fluids help remove residual moisture from metal surfaces after washing, rinsing, machining, hydrotesting, or exposure to condensation. They may also leave behind a protective corrosion-inhibiting film.

Cleaners and Degreasers

Corrosion-inhibiting cleaners help remove machining oils, grease, dirt, metal fines, and process residues while reducing the risk of flash corrosion during cleaning and preparation.

Protecting Work-in-Progress Parts

Machined and fabricated components are often most vulnerable while waiting for the next manufacturing step. Bare metal surfaces may be exposed to humid plant air, fingerprints, condensation, process water, and corrosive residues.

Cortec® in-process corrosion inhibitors can help protect parts during:

• Overnight and weekend production delays
• Movement between machining and assembly areas
• Quality inspection and rework holds
• Temporary indoor storage
• Post-wash drying and staging
• Packaging and shipment preparation

Metal Compatibility

Cortec® offers products for ferrous metals, non-ferrous metals, and multi-metal assemblies. Depending on the formulation, applications may include:

• Carbon steel and stainless steel
• Cast iron
• Galvanized steel
• Aluminum
• Copper and brass
• Zinc and other selected alloys

Product compatibility should be confirmed for the specific metal, alloy, surface finish, coating, and manufacturing process before full-scale use.

Choosing a Metalworking Fluid or Rust Preventative

Important selection factors include:

• Machining, forming, cleaning, or preservation operation
• Metal and alloy types being processed
• Water-based, synthetic, semi-synthetic, or oil-based system
• Required lubrication and cooling performance
• Fluid concentration and water quality
• Indoor or outdoor exposure
• Length of in-process storage or shipment
• Desired protective film type
• Compatibility with downstream finishing operations
• Cleaning or removal requirements
• Application equipment and operating temperature

Application Methods

Depending on the selected product, Cortec® metalworking fluids and corrosion preventatives may be applied by:

• Adding the product to a compatible circulating fluid system
• Spraying or misting
• Dipping or immersion
• Brushing or rolling
• Flow coating
• Metered application at the tool or workpiece
• Fogging enclosed machinery or equipment

Follow the current technical data sheet for dilution, concentration, mixing sequence, application temperature, drying, removal, and equipment-cleaning instructions.

Fluid Concentration and Process Control

Correct concentration is important for machining performance, fluid stability, corrosion protection, and service life. Concentration that is too low may reduce protection and lubrication, while excessive concentration may increase residue, foaming, cost, or downstream cleaning requirements.

Water quality, pH, microbial activity, tramp oil, metal fines, operating temperature, and fluid contamination should also be monitored as part of a complete metalworking-fluid management program.

Benefits of Cortec® Metalworking Products

Testing Before Full-Scale Use

A controlled trial is recommended before introducing a new metalworking product into production. Testing should evaluate machining performance, corrosion protection, residue, foaming, fluid stability, surface appearance, filtration, cleaning, coating adhesion, and compatibility with downstream processes.

The current technical data sheet and safety data sheet should be reviewed before handling, mixing, applying, or disposing of any metalworking product.

Are Cortec® metalworking products water-based?

Cortec® offers water-based, semi-synthetic, oil-based, and biobased formulations. The best choice depends on the operation, required lubricity, metal type, fluid system, corrosion risk, and downstream processing requirements.

Can Cortec® additives be added to an existing fluid?

Certain Cortec® products are designed as additives for compatible metalworking fluids, lubricating oils, hydraulic oils, or water-based systems. Compatibility and concentration should be confirmed through technical review and controlled testing before full-scale use.

Do metalworking rust preventatives need to be removed?

Removal depends on the product and the next manufacturing step. Some thin films can remain on the part, while others should be removed before painting, plating, welding, assembly, or final finishing.

Can these products protect multiple metals?

Many Cortec® products provide multi-metal protection, but compatibility varies by formulation. The specific metals and alloys in the process should be identified before selecting a product.

Can Cortec® products help prevent flash rust after washing?

Yes. Selected corrosion-inhibiting cleaners, rinse additives, water-displacing products, and rust preventatives can help reduce flash corrosion after compatible cleaning or rinsing operations.

Can ECORR Systems help select the right metalworking product?
