capabilities. Certified coaters can show, through demonstrated audit performance measurement, that they have the capabilities to correctly clean, coat and cure products to produce quality coated parts.
Coil-anodized aluminum provider Lorin Industries has announced details of its electrochemical anodizing process. Pio- neered by the Muskegon, MI-based firm, the process’ protective aluminum-oxide layer, known as the anodic layer, is grown at the molecular level from
“Process measurement and repeata- bility are key to giving customers confidence that a certified finishing operation has the processes in place to do the job well,” notes Trena Benson, PCI’s executive direc- tor. “Those who pass the comprehensive audit demonstrate that they have the ability to meet a high professional standard in the industry.”
the surface of the metal,
2500 to 25,000 times thick-
er than that of a naturally
occurring aluminum-oxide layer.
Not a coating, but rather a protective
outer layer of the metal itself bonded together at the molecular level, it provides corrosion and scratch protection. Only a few metals can be protectively anodized in this way.
The program offers two certification types: PCI 3000 certification for custom coaters and PCI 4000 certification for original-equipment manufacturers.
Controlling the oxidation process through continuous coil anodizing creates a clear, translucent aluminum-oxide layer that reveals the natural beauty of a material. This anodic layer also can be colored for a specific look, even simulating other natural metals. Additionally, because this layer is created through the continuous-coil process, the color and finish are consistent over every square inch. of the aluminum. And, unlike painted or coated products, Lorin anodized aluminum reportedly will not chip, flake or peel.
Russia’s Severstal Launches New Line for Polymer-Coated Rolled Steel Products
The translucent crystalline structure of the anodic layer allows the aluminum to reflect and refract light in ways that other metals, paints, or coatings don’t, according to company officials. This helps the material, and thus any product made with it, come alive. A part of the corundum family of gemstones, including sapphire, and second only to diamonds in terms of hardness, the crystalline aluminum-oxide layer is key in achieving aesthetics, performance and durability.

PAO Severstal, a vertically integrated steelmaking company in Cherepovets, Russia, has launched a production line, expected to produce 200,000 tons of polymer-coated rolled steel products and 400,000 tons of galvanized steel per year. The polymer-coating unit produces 22 tints and has successfully tested the application of a chromium-free coating for household appliances. Severstal also plans on testing the application of hot lamination and decorative film.

Powder Coating Institute Updates Certification Programs
Operating under the mantra “Powder Coating Done Right,” the Powder Coating Institute (PCI), Taylor Mill, KY, has launched its reengineered and expanded certification programs. PCI certification is an extensive audit program that evaluates the candidate’s business practices, process elements, equipment, maintenance practices and quality-control

Corrosion Protection
Cortec Corp.’s FlashCorr VpCI, a blend of surfactants, chelating agents and corrosion inhibitors, protects metal surfaces from cor- rosion. It can be applied to sand-blasted, water-blasted and wire-brushed surfaces to stabilize and protect against flash corrosion
"We believe that with the launch of the polymer coating line at Cherepovets, we will see a significant improvement in the supply of polymer-coated products to our company,” says Denis Voronov, director for supply and logistics of Metal Profile Company LLC, “as well as a noticeable improvement to the entire Russian market, given the seasonal fluctuations in demand. Now we can fully meet the needs of our customers even at peak periods, with no help from import suppliers. In addition, these new products will contribute to Rus- sia’s increasing share of high-quality pre- mium products.”

before application of primers, paints and protective coatings. The product reduces application costs and improves adhesion, thus allowing effective and long-term performance of protective-coatings systems. Applications include salt spreaders, snow plows, blowers, boats, commercial vehicles, etc. It also is highly recommended for protection of machinery and engine blocks as well as marine equipment.
