ECORR Systems provides Cortec® VpCI® corrosion-inhibiting primers for preparing and protecting metal surfaces before the application of compatible industrial topcoats.
As an Authorized Cortec® Distributor, ECORR Systems offers water-based primers, rust-converting primers, wash primers, epoxy primers, urethane primers, and direct-to-metal coating systems for ferrous, non-ferrous, and multi-metal applications.
A primer forms the foundation of a protective coating system. It helps the topcoat adhere to the substrate while providing an additional layer of protection between the metal and its surrounding environment.
Cortec® VpCI® primers incorporate corrosion-inhibiting technology directly into the coating layer closest to the metal surface. Depending on the formulation, these primers may improve adhesion, convert existing rust, protect multiple metals, tolerate demanding exposure, or support a compatible multi-coat system.
Rust-converter primers are formulated for steel surfaces where complete removal of tightly bonded corrosion is difficult or impractical. They react with the remaining rust and create a more stable surface for a compatible topcoat.
Wash primers help improve coating adhesion to challenging substrates such as aluminum, stainless steel, galvanized steel, and plated metal. They are typically applied as a thin preparatory layer before a compatible primer or topcoat.
Water-based acrylic primers can provide fast drying, corrosion protection, and easier application or cleanup than many traditional solvent-based coating systems. Certain formulations can function as both a primer and topcoat.
Epoxy primers provide strong adhesion, film strength, and resistance to demanding industrial conditions. Selected products can be used in coating systems exposed to chemicals, outdoor environments, or immersion conditions.
Urethane primers form a durable coating layer for industrial and marine applications. Depending on the formulation, they may provide direct-to-metal protection, flexibility, and resistance to moisture or aggressive environments.
Direct-to-metal primers are applied directly to properly prepared metal without a separate preparatory primer. Some Cortec® products can also serve as a complete primer and topcoat system for approved applications.
» CorrVerter® Rust Converter Primer A fast-drying, water-based primer that converts tightly bonded rust into a hydrophobic passive layer and creates a more consistent surface for compatible topcoating.
» VpCI®-373 Wash Primer A fast-drying, water-based acrylic primer that promotes adhesion on difficult-to-coat surfaces such as aluminum, galvanized steel, stainless steel, and other plated metals.
» VpCI®-375 Water-Based Primer A water-based acrylic coating that can be used as a primer or complete primer-and-topcoat system in approved applications involving carbon steel, copper, and other compatible substrates.
» VpCI®-395 Epoxy Primer A fast-drying, two-component water-based epoxy primer designed for direct-to-metal application and demanding industrial exposure.
» VpCI®-396 Urethane Primer A high-solids, moisture-cure urethane primer that provides direct-to-metal multi-metal protection and serves as a durable foundation for a compatible topcoat.
CorrVerter® is designed for applications where rust is present and complete abrasive blasting may not be practical. It converts the remaining tightly bonded corrosion into a passive layer that can be covered with a compatible coating.
CorrVerter® does not eliminate all surface-preparation requirements. Loose rust, scale, dirt, grease, oil, salts, and other contaminants should be removed before application. It is intended for rusted ferrous surfaces and should not be treated as a universal primer for every substrate.
Aluminum, galvanized steel, stainless steel, and plated surfaces can present adhesion challenges because they are smooth, chemically resistant, or protected by naturally occurring surface layers.
VpCI®-373 is designed to improve adhesion on these difficult substrates. It is generally applied as a thin wash-primer layer before the selected compatible coating system. Substrate preparation and topcoat compatibility should be confirmed before application.
The appropriate coating structure depends on the substrate, environment, performance requirements, and available application time.
Correct surface preparation is critical to primer adhesion and coating-system performance. Requirements vary by product, but surfaces should generally be clean, dry, and free from oil, grease, dirt, salts, dust, loose rust, mill scale, and incompatible coatings.
Preparation methods may include:
The required preparation standard should be determined from the primer technical data sheet, substrate condition, exposure environment, and project specifications.
Important factors to consider include:
Depending on the selected Cortec® primer, application methods may include:
Product mixing, induction time, thinning, equipment selection, wet-film thickness, dry-film thickness, recoat interval, pot life, temperature, humidity, and curing requirements should follow the current technical data sheet.
Not every primer is compatible with every topcoat. Differences in resin chemistry, solvent strength, curing mechanism, recoat interval, and film thickness can affect adhesion and coating performance.
Before applying a topcoat:
Temperature, humidity, ventilation, condensation, and substrate temperature can affect coating application and cure. Applying a primer outside its approved conditions may result in slow curing, poor adhesion, bubbling, cracking, or premature coating failure.
Confirm that the substrate is dry and within the recommended temperature range. Outdoor application should be planned around changing weather, rain, dew, and temperature conditions.
Review the current technical data sheet and safety data sheet before mixing or applying any primer. Follow all instructions regarding ventilation, personal protective equipment, storage temperature, mixing ratios, pot life, application equipment, cleanup, and disposal.
Protect water-based products from freezing when required. Two-component and moisture-cure products may have special mixing, storage, and partially used container requirements.
» High-Performance Coatings Industrial topcoats, direct-to-metal coatings, temporary coatings, and specialty coating systems.
» Surface Preparation Products for cleaning, removing corrosion, and preparing metal before priming or coating.
» Cleaners and Degreasers Cleaning products for removing grease, oil, dirt, residues, and other surface contaminants.

ECORR Systems is an Authorized Cortec® Distributor helping manufacturers, industrial facilities, contractors, fabricators, maintenance teams, and asset owners select primers for new construction, repair, refurbishment, and corrosion-control projects.
ECORR Systems can help evaluate the substrate, existing corrosion, surface-preparation method, exposure environment, topcoat, application equipment, and required service life to identify an appropriate Cortec® primer and coating system.
A corrosion-inhibiting primer places protective chemistry directly against the prepared metal surface while helping the compatible topcoat adhere. This creates a stronger foundation for the complete coating system.
CorrVerter® is formulated for rusted ferrous surfaces, but loose rust, scale, oil, dirt, and other contamination must still be removed. Other Cortec® primers may require substantially cleaner or abrasive-blasted surfaces.
CorrVerter® does not remove rust in the same way as a chemical rust remover or abrasive blasting. It converts tightly bonded remaining rust into a passive layer that can receive a compatible topcoat.
VpCI®-373 is designed to promote adhesion on difficult substrates such as aluminum, galvanized steel, stainless steel, and plated surfaces. Final selection depends on the substrate, preparation method, topcoat, and exposure environment.
No. Some Cortec® coatings are designed for direct-to-metal application or can function as both a primer and topcoat. A separate primer may still improve adhesion, corrosion protection, or coating-system durability in demanding environments.
It may be possible, but compatibility should be confirmed before full application. Resin chemistry, solvents, curing mechanism, recoat window, and service conditions can affect adhesion and performance.
Selected primers, including certain epoxy and urethane systems, may be used in approved immersion applications. The specific liquid, temperature, surface preparation, topcoat, curing time, and operating conditions must be reviewed.
Yes. ECORR Systems can help identify compatible surface-preparation products, primers, topcoats, and temporary protective coatings based on the substrate and service environment.
