CASE HISTORY SPOTLIGHT: Case History #769: Stopping Underbody Rust on Collector’s Car

In 2008, the owner of a 1947 Chrysler Windsor decided to passivate the rusty front underbody and interior floor of his collector’s car. He chose to try Cortec® Coatings based on a good experience working with Cortec® products in the Cortec® sample department.

He started his winter restoration by scraping all the grease and grime off the front wheel drums, shock absorbers, and undercarriage. He applied just enough CorrVerter® Rust Converter Primer to stop the rust and followed this with a topcoat of VpCI®-386 Black when the CorrVerter® cured. He used the same two coatings on the rusty floor inside the car.


The owner was impressed with the coatings, especially since he did not have to worry about using flammable products or enduring unpleasant fumes while working in his garage with the heater on and the door closed. When doing brake work almost 14 years later, he was impressed to find that these areas were still clean, solid, and rust-free, with no “rust creep” coming out of the nuts and bolts.

CASE HISTORY SPOTLIGHT: Case History #616: Coating Refrigerator Coils

A refrigerator coil manufacturer was unsatisfied with the solvent-based paint they were using to coat the coils. Workers disliked the strong solvent smell and associated health hazards. Long-term corrosion protection was also deficient. By switching to water based VpCI®-386 in their dip tank, the manufacturer was able to reduce VOCs while improving corrosion performance and the worker environment.

CASE HISTORY SPOTLIGHT: Case History #783: Better Corrosion Protection with Less Paint

A tube steel manufacturer needed a water-based corrosion inhibitor coating for the OD (outer diameter) of oil and gas industry pipes. In addition to protecting pipe externals until commissioning, the coating needed to be applied at 1 mil (25 µm) DFT, meet zero VOC requirements, and force-dry in an oven at 140 °F (60 °C) before stenciling.

A trial was done using Cortec® EcoShield 386 FD on several thousand pipes left to sit outside for one year near the Gulf of Mexico. The pipes were hydrotested before the coating was applied and then force dried for 22 minutes. At the end of a year in outdoor storage, the coating showed excellent 5B adhesion, and there was no rust on pipe ODs. Three other trials did similarly well.

The client was very satisfied with the product performance and planned to use it at other facilities. In contrast to the competitor product, EcoShield® 386 FD helped the manufacturer achieve longer protection and meet local VOC requirements at only 0.04 lbs/gal (5 g/L) VOC. It also allowed the manufacturer to save money by using less paint.

CASE HISTORY SPOTLIGHT: Case History #482: Cooling Tower Preservation

After successfully using Cortec® products in other areas of operation, one manufacturer decided to try to achieve longer lasting protection than with traditional paint by using Cortec® Coatings on a cooling tower exterior. The two parts of VpCI®– 395, a two-component (2K) primer, were mixed and given time for crosslinking, then applied to the metal surface that had been cleaned with acetone. Two coats of VpCI®-395 primer were used, followed by a topcoat of VpCI®-392 clear. The customer’s positive impressions of Cortec® products continued along with an interest in using more of them.

CASE HISTORY SPOTLIGHT: Case History #735: Corrosion Preventative Maintenance on Fertilizer Loaders

VpCI-391

Front-end loaders for moving high volumes of deicing salts and/or fertilizers at ports along the Ohio River had a habit of corroding quickly. The aggressive environment forced the company to search for a new preventative maintenance plan that would keep the equipment from looking 10 years old in just one year and reduce the normal replacement frequency of two to three years.

VpCI®-391 is now applied once a year during the slow season. The equipment is power washed and dried before receiving a complete overspray of VpCI®-391 on the front, back, top, and bottom—everything except the windows. The client loved the product and has been using it for more than a decade to extend equipment service life—no special permitting required for this low-VOC coating!

CASE HISTORY SPOTLIGHT: Case History #336: Protective Coatings for European Extrusion Plant

The owner of a film extrusion plant in Croatia needed a full protective coatings system that was cost-effective, easy to apply, and took the environment into consideration. Cleaning, adhesion, and overall appearance were other important factors.

All silos, light poles, and the floor were first cleaned with VpCI®– 414 Cleaner/Degreaser (sometimes diluted 15% with water). One coat of VpCI®-386 Green was applied to the silos. VpCI®– 386 Green was also used as a topcoat on the light poles after priming them with VpCI®-373 to improve adhesion to the galvanized surface. MCI®-2026 Concrete Primer and MCI®-2026 Floor Coating were applied to the floor. A Cortec® water-based coating system was also applied to the extrusion line before the manufacturer shipped it from Italy to Croatia.

The Cortec® Coatings allowed the extrusion plant to easily apply a color-coded coatings system that promotes safety and corrosion protection while employing several water-based products.

CASE HISTORY SPOTLIGHT: Case History #618: Corrosion Protection of Guy-Wire Clamps

A corrosive environment of strong wind and blowing sand near the ocean led to corrosion on guy-wire clamps anchoring a cell tower in Brazil. The solution was to brush off loose rust, clean the clamps with VpCI®-418, and coat them with VpCI®-368, a wax-like, removable coating. This will be an important step to mitigate future corrosion in such a severe environment and thus prolong the service life of the critical components that keep the cell tower standing safely.

CASE HISTORY SPOTLIGHT: Case History #737: Cortec® Coatings for Forklift Preventative Maintenance

A fork truck rental company found its equipment seriously damaged by corrosion after leasing it for use in the corrosive environment of a sauerkraut plant. In order to arrest the corrosion and preserve resale value, the company began a monthly preventative maintenance program using Cortec® Coatings. CorrVerter® was used to passivate existing rust, and EcoShield® 386 was applied to all painted metal surfaces. Moving parts that could not be painted were protected with CorShield® VpCI® -369. Exposed electrical connections were sprayed with ElectriCorr® VpCI® -239. These products are reapplied as needed during monthly maintenance and have led to a huge improvement in rust prevention. The customer rarely has to use CorrVerter® anymore and is able to keep the equipment in resalable condition during the lease period.
