Fork trucks leased to a sauerkraut plant quickly lost resale value from exposure to a corrosive environment of brine, salt, and sauerkraut. The rental company therefore began applying Cortec® products as needed during monthly maintenance to slow down the corrosion. CorrVerter^® Rust Converter Primer was used to passivate rusty surfaces. EcoShield^® VpCI^®-386 was applied over painted metal surfaces, and CorShield^® VpCI^®-369 was used on moving metal parts. ElectriCorr^™ VpCI^®-239 was sprayed on exposed electrical connections. The rental company has seen a significant difference in the ability of the equipment to remain in resalable condition to the end of the lease period and has implemented the same preventative maintenance strategy on equipment leased and used in another corrosive industrial environment.

A vehicle maintenance workshop in Europe was in the business of restoring car rims. They needed a way to deal with existing rust and protect against further rust long-term. Their solution was to remove loose rust with a wire brush and passivate the remaining rust with Cortec® CorrVerter®. VpCI®-396 Aluminum was applied as a topcoat, and VpCI®-368 D was used as an additional layer of protection for outdoor storage of the rims. The customer was very satisfied with the products and continued to use them on a regular basis.

The ends of 30 feet (9 m) tubes used in fire protection systems were being missed during a fast-paced painting process on the production line. The manufacturer needed a rust preventative that could protect the ends of the tubes so they would be aesthetically pleasing to customers after being bundled and stored outside for 9-12 months.

The manufacturer decided to test EcoLine® 3690 biobased coating on a small bundle of bare steel pipes. A second bundle was coated with water-based paint for comparison. The bundles were stored outside for about eight months. At the end of the trial, the manufacturer was impressed with the performance of EcoLine® 3690 and adopted it as a replacement for the solvent-based rust preventative previously used to protect the ends of the tube bundles.

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.

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.

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.

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.

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!

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.
