Due to the strong solvent smell, hazards, and inadequate corrosion protection of the solvent-based paint they were using, a refrigerator coil manufacturer decided to switch to VpCI®-386. They kept this water-based paint in their dip tank, circulating the product to keep it mixed and covering the tank when not dipping the coils. As a result, the manufacturer was able to reduce their VOCs while also achieving superior corrosion protection.

The owner of a manufacturing plant in Europe needed protective coatings with customized colors on both interior and exterior details. Desirable traits included cost effectiveness, ease of application, and environmental responsibility.

Silos, light poles, and the floor were cleaned with a solution of VpCI^®-414 Cleaner/Degreaser. From there, silos were coated with VpCI^®-386 Green, galvanized light poles were coated with VpCI^®-373 and VpCI^®-386 Green, and the floor was coated with MCI^®-2026 Concrete Primer and MCI^®-2026 Floor Coating. The extrusion line was coated with Cortec’s water-based coating technology prior to shipment from Italy. Color coding was used in certain areas as warnings against heat exposure or slippage on stairs. The system provided a variety of water-based or low VOC options with precautions against safety hazards and corrosion on metal surfaces.

A third-party packager of all-time buys for a major automaker was looking for a new rust preventative to use on parts packed for up to 10 years of aftermarket storage. A solvent-based rust preventative had been used for decades but was difficult to remove and raised concerns for workers and the environment. To find a possible alternative, they requested that Cortec^® Laboratories test the performance of EcoLine^® 3690 (a canola-oil based rust preventative that contains 72% USDA certified biobased content) according to automaker specs.

Results were considered successful. One camshaft came out of salt spray testing in very good condition with only some small corrosion spots (after one more day in testing than required). The other camshaft and cylinder head also came through humidity testing in very good condition except for some areas on intricate springs that had been difficult to coat by hand and areas where water had pooled on the cylinder head.

EcoLine^® 3690 was written into the automaker’s specs for aftermarket engineering processes. The packaging company began using it when packing crankshafts, camshafts, and cylinder heads for long-term storage of all-time-buys and was very happy with the results and worker benefits.

A manufacturer of front-end loaders and skid steers needed corrosion protection on unpainted metal components during outdoor storage for up to six months or a year. The customer had been using a sticky oil-based product that looked terrible because it collected dirt and bugs. It was also at risk of washing off in harsh storms.

In the search for a removable rust preventative product that looked better, had low VOCs, and only needed to be applied once, the manufacturer (who had a longstanding relationship with Cortec^®) tested VpCI^®-391 to ensure compatibility with fiberglass and painted areas of the equipment. This confirmed, they started using VpCI^®-391 on unpainted metal parts and other sensitive areas, including wheel rims, bolt heads, and hydraulic boxes. The product offered effective protection. Complaints about appearance stopped, and equipment distributors often leave VpCI^®-391 on permanently. Thanks to VpCI^®-391, the company has successfully replaced an oil-based product with one that is water-based, has low VOCs, and looks good.

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.
